+
+2013-10-01 Paul Smith <psmith@gnu.org>

+
+2013-09-29 Paul Smith <psmith@gnu.org>
+
+ * output.c (output_dump): Always write Enter/Leave messages to stdio.
+ (log_working_directory): This now always writes to stdio, so we
+ don't need the struct output parameter anymore.
+ (output_start): Show the working directory when output_sync is not
+ set or is recursive.
+ * main.c (main): Ensure the special "already shown Enter message"
+ token is removed from MAKE_RESTARTS before the user can see it.
+ * function.c (func_shell_base): If the output_context stderr
+ exists but is invalid, write to the real stderr.
+ Fixes suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>.

+ * w32/compat/posixfcn.c: Invert the test for NO_OUTPUT_SYNC.
+
+ * guile.c (GSUBR_TYPE): Pre-2.0 Guile doesn't provide a typedef

+
+2013-09-22 Paul Smith <psmith@gnu.org>
+
+ * configure.ac: Update version to 3.99.92.

+
+ * implicit.c (pattern_search): After second expansion be sure to
+ handle order-only markers inside the expansion properly.
+ Fixes Savannah bug #31155.
+
+ * guile.c (guile_define_module): Technically a void* cannot

+
+ * guile.c (guile_gmake_setup): Don't initialize Guile so early.
+ (func_guile): Lazily initialize Guile the first time the $(guile ..)

+
+ * makefile.com: Add output to the filelist.
+ * output.c (va_copy): Add an implementation of this macro for VMS.

+
+2013-09-21 Paul Smith <psmith@gnu.org>

+
+ * configure.ac: Don't set OUTPUT_SYNC.

+
+ * main.c (make_sync): Define a context for syncing while reading
+ makefiles and other top-level operations.
+ (main): If we request syncing, enable it while we are parsing
+ options, reading makefiles, etc. to capture that output. Just
+ before we start to run rules, dump the output if any.
+ (die): Dump any output we've been syncing before we die
+ * output.h (OUTPUT_SET): Disable output_context if not syncout.
+
+ Stderr generated from shell functions in recipes should be synced.

+ avoid magic numbers.
+ (child_execute_job): Take a FD for stderr.
+ * job.c (child_execute_job): Handle STDERR FD's in addition to
+ stdin and stdout.

+ parameter. Instead of performing the dup() here, send it to
+ child_execute_job() where it's already being done.
+ * function.c (func_shell_base): Pass the OUTPUT_CONTEXT stderr to
+ child_execute_job() if it's set, otherwise FD_STDERR.
+ * main.c (main): Pass FD_STDERR to child_execute_job().
+
+2013-09-19 Paul Smith <psmith@gnu.org>
+
+ * main.c (main): Set MAKE_RESTARTS to negative before re-exec if
+ we've already generated an "Entering" message. If we are started
+ and notice that MAKE_RESTARTS is negative, assume we already wrote
+ "Entering" and don't write it again.
+
+2013-09-18 Paul Smith <psmith@gnu.org>
+
+ * main.c (main): Set starting_directory before we write any
+ errors. Fixes Savannah bug #40043.
+
+2013-09-16 Eli Zaretskii <eliz@gnu.org>
+
+ * output.c [WINDOWS32]: Include windows.h and sub_proc.h, to avoid
+ compiler warnings for CLOSE_ON_EXEC.
+
+2013-09-16 Paul Smith <psmith@gnu.org>
+
+ * configure.ac: Update version to 3.99.91.
+ * NEWS: Ditto.
+
+2013-09-15 Paul Smith <psmith@gnu.org>
+
+ * doc/make.texi (Error Messages): Add a bit more info to the
+ section on static pattern errors, since they're common.
+ Fixes Savannah bug #31326.
+
+ * read.c (eval_makefile): If the file open fails with an
+ unrecoverable error, stop now rather than trying to make it.
+ Fixes Savannah bug #27374.
+
+ * main.c (main): Perform the validation of the jobserver FDs
+ early, before we read makefiles, to ensure that something hasn't
+ opened and used those FDs for some other reason.
+ Fixes Savannah bug #39934.
+
+ * main.c (main): Don't set MAKEFLAGS in the environment when we
+ restart. We have the original command line flags so keep the
+ original MAKEFLAGS settings as well.
+ Fixes Savannah bug #39203.
+
+2013-09-14 Paul Smith <psmith@gnu.org>
+
+ * main.c (decode_debug_flags): Add support for the "n" flag to

+ * misc.h: Ditto.
+ * output.h: Ditto.
+ * main.c (main): Move stdio init into output.c:output_init().
+ Change open_tmpfile() to output_tmpfile().
+ * output.c: Rename open_*() to output_*(). set_append_mode() and
+ open_tmpfd() are static.
+ (_outputs, log_working_directory): Accept a struct output and
+ print to that rather than the global context.
+ (output_dump): In recurse mode print enter/leave once for the
+ whole makefile.
+ (output_init): Initialize this processes stdio as well as child's.
+
+ * vmsjobs.c: Reformat to be closer to convention.
+
+2013-09-12 Paul Smith <psmith@gnu.org>
+
+ Rework output to handle synchronization and directory logging more
+ reliably.
+
+ * output.c: New file. Implement lazy synchronization and
+ directory logging so that we manage them "just in time", and the
+ destination of the output is set via a global state variable.
+ * output.h: New file.
+ * function.c (func_shell_base): Ensure the output is set up before
+ running a shell command, in case it writes to stderr.
+ (func_error): Use outputs() to generate output.
+ * job.h (struct child): Add struct output to track the child's output.
+ * job.c: Use struct output in the child structure to track output.

+ the output_sync handling to output.c.
+ (child_error): Set output, then use simple message() and error()
+ not _s versions.
+ * main.c (log_working_directory): Moved to output.c
+ (trace_option, decode_trace_flags) Remove. Remove support for
+ different trace modes; we don't use it anymore.
+ (die) Invoke output_close() before we exit.
+ * misc.c (message_s, error_s): Removed; no longer needed.
+ (message, error, fatal, perror_with_name, pfatal_with_name): Moved
+ to output.c.
+ * makeint.h: Remove message_s(), error_s(), and
+ log_working_directory(). Remove the TRACE_* macros.

+ * Makefile.am: Add new files.
+ * NMakefile.template: Ditto.
+ * SMakefile.template: Ditto.
+ * build_w32.bat: Ditto.

+
+2013-08-22 Petr Machata <pmachata@redhat.com>
+
+ * function.c (func_shell_base): Get rid of any avoidable limit on
+ stack size for processes spawned via $(shell).
+
+2013-07-22 Paul Smith <psmith@gnu.org>
+
+ * implicit.c (pattern_search): Use PARSE_SIMPLE_SEQ() even for
+ non-second expansion prerequisites, to handle globbing in patterns.
+ Fixes Savannah bug #39310.
+
+ * dep.h (PARSE_SIMPLE_SEQ): Macro for simple file sequence parsing.
+ * default.c (set_default_suffixes): Use it.
+ * file.c (split_prereqs): Ditto.
+ * main.c (main): Ditto.
+ * read.c (eval): Ditto.
+ * rule.c (install_pattern_rule): Ditto.
+ * file.c (split_prereqs): Use PARSEFS_NONE instead of 0.
+
+2013-07-21 Paul Smith <psmith@gnu.org>
+
+ Cleanups detected by cppcheck. Fixes Savannah bug #39158.
+ * arscan.c (ar_scan): Reduce the scope of local variables.
+ * dir.c (vms_hash): Ditto.
+ (find_directory): Ditto.
+ (file_impossible_p): Ditto.

+
+ * job.c (assign_child_tempfiles): Assign OUTFD to -1 for safety.
+ (start_job_command): Don't test output_sync and sync_cmd: redundant.
+ Changes suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>.
+
+2013-07-14 Paul Smith <psmith@gnu.org>
+
+ * filedef.h (update_status): Convert UPDATE_STATUS from a char to
+ an enumeration. Some systems declare "char" to be "unsigned"
+ which broke the code (which expected to be able to use -1 as a
+ flag). Using magic values was unpleasant, so rather than just
+ force "signed char" I reworked it to use an enum.
+
+ * dep.h (update_goal_chain): Return an update_status value not int.
+ * remake.c (touch_file): Ditto.
+ (update_goal_chain): Track the update_status enum.
+
+ * file.c (enter_file): Use new enumeration values with update_status.

+ (complain): Ditto.
+ (update_file_1): Ditto.
+ (notice_finished_file): Ditto.
+ (remake_file): Ditto.
+ * vmsjobs.c (vmsHandleChildTerm): Ditto.
+
+2013-07-09 Paul Smith <psmith@gnu.org>
+
+ * implicit.c (pattern_search): Keep a local copy of the number of
+ deps in deplist: the global max might change due to recursion.
+ Fixes a bug reported by Martin d'Anjou <martin.danjou14@gmail.com>.
+
+2013-06-28 Paul Smith <psmith@gnu.org>
+
+ * misc.c (set_append_mode): Set the O_APPEND flag on a file descriptor.
+ (open_tmpfd): Set append mode on the temporary file descriptor.
+ * main.c (main): Set append mode on stdout and stderr.
+ * makeint.h (set_append_mode): Declare it.
+
+2013-06-22 Eli Zaretskii <eliz@gnu.org>
+
+ * build_w32.bat (LinkGCC): Prevent a comment from being displayed
+ at build time.
+
+ * job.c (construct_command_argv_internal) [WINDOWS32]: Use
+ case-insensitive comparison with internal commands of non-Unix
+ shells.
+
+ * main.c (find_and_set_default_shell): Don't use file_exists_p or
+ dir_file_exists_p, as those call readdir, which can fail if PATH
+ includes directories with non-ASCII characters, and that would
+ cause Make to fail at startup with confusing diagnostics. See
+ https://sourceforge.net/mailarchive/message.php?msg_id=30846737
+ for the details.
+
+2013-06-22 Paul Smith <psmith@gnu.org>
+
+ Improve performance by using a character map to determine where we
+ want to stop searching strings, rather than discrete comparisons.
+
+ * read.c (find_char_unquote): Pass a stop map instead of various
+ flags and use that to check when to stop parsing the string.
+ (eval): Use the new find_char_unquote() calling signature.
+ (remove_comments): Ditto.
+ (unescape_char): Ditto.
+ (find_percent_cached): Ditto.
+ (parse_file_seq): Use a stop-map flag.
+ * main.c (stopchar_map): Character map definition.
+ (initialize_stopchar_map): Initialize the map definition.
+ (main): Invoke the map initialization function.
+ * misc.c (end_of_token_w32): Remove unused function.
+ * dir.c (dosify): Use STOP_SET to check for stop chars.
+ * main.c (main): Ditto.
+ * misc.c (end_of_token): Ditto.
+ * function.c (subst_expand): Ditto.
+ (func_notdir_suffix): Ditto.

+ (abspath): Ditto.
+ * job.c (is_bourne_compatible_shell): Ditto.
+ * variable.c (parse_variable_definition): Ditto.
+ * read.c (eval): Ditto.
+ (conditional_line): Ditto.

+ * function.c (string_glob): Ditto.
+ * implicit.c (pattern_search): Ditto.
+ * rule.c (install_pattern_rule): Ditto.
+ * main.c (main): Ditto.
+
+2013-06-21 Paul Smith <psmith@gnu.org>
+
+ * main.c (verify_flag): Global variable to determine whether to
+ verify the database or not.
+ (decode_debug_flags): If debug mode, enable verify_flag.
+ (main): If MAKE_MAINTAINER_MODE, enable verify_flag, otherwise not.
+ (die): Only verify the database if verify_flag is set.
+ * file.c (enter_file): Don't check caching unless verify_flag.
+ * makeint.h: Export verify_flag.
+
+2013-05-27 Paul Smith <psmith@gnu.org>
+
+ * variable.c (define_automatic_variables): Create a new variable
+ MAKE_HOST.
+
+2013-05-27 Hartmut Becker <becker.ismaning@freenet.de>
+
+ * function.c (func_shell_base) [VMS]: Support VMS.
+ * makefile.com [VMS]: Ditto.
+ * makefile.vms [VMS]: Ditto.
+ * makeint.h [VMS]: Ditto.
+ * vmsjobs.c [VMS]: Ditto.
+ * job.h: Define RECORD_SYNC_MUTEX() when OUTPUT_SYNC is not set.
+ * load.c (unload_file): Fix signature if MAKE_LOAD is not set.
+
+2013-05-26 Paul Smith <psmith@gnu.org>
+
+ * remake.c (f_mtime): Ensure that archive file names are in the
+ string cache. Fixes Savannah bug #38442.
+
+ * read.c (readline): To be safe, move the entire buffer if we
+ detect a CR. Fixes Savannah bug #38945.
+
+ * job.c (new_job): Compare OUT to the beginning of the OUT
+ var/function, not IN. Fixes Savannah bug #39035.
+
+2013-05-22 Paul Smith <psmith@gnu.org>
+
+ * main.c (switches[]): Order switches so simple flags all come first.
+ (define_makeflags): Rework to make option passing more
+ reliable and the code less tricksy. Ensure simple flags are kept
+ in the initial batch of flags. Do not allow any flags with
+ options in that batch. If there are only non-simple flags MAKEFLAGS
+ begins with ' '.
+ (print_data_base): Print the version. Fixes part of Savannah #35336.
+
+ * read.c (eval_buffer): Initialize lineno.
+
+2013-05-18 Alexey Pavlov <alexpux@gmail.com> (tiny change)
+
+ * w32/Makefile.am (libw32_a_SOURCES): Add compat/posixfcn.c.
+
+ * configure.ac (OUTPUT_SYNC): Define for mingw32 target.
+
+ * job.c (construct_command_argv_internal) <sh_cmds_dos>
+ [WINDOWS32]: Add "move". Fixes Savannah bug #30714.
+
+ * guile.c: Move inclusion of makeint.h before gnumake.h. This
+ order must be observed when building Make, because gnumake.h must
+ be included with GMK_BUILDING_MAKE defined, which makeint.h
+ already does. Otherwise, the linker will look for, and fail to
+ find, gmk_* functions in some external dynamic library.
+
+2013-05-17 Benno Schulenberg <bensberg@justemail.net>
+
+ * main.c (decode_output_sync_flags): Fix output message.

+
+ * ALL: Update copyright.
+
+ * hash.c (CALLOC): Use xcalloc() to handle out of memory errors.
+
+ * makeint.h: Prototype new unload_file() function.
+ * load.c (unload_file): Create a function to unload a file.
+ (struct load_list): Type to remember loaded objects.
+ (loaded_syms): Global variable of remembered loaded objects so we
+ can unload them later. We don't have to remove from the list
+ because the only time we unload is if we're about to re-exec.
+ (load_object): Remove unneeded extra DLP argument.
+ (load_file): Remove unneeded extra DLP argument.
+ * filedef.h (struct file): Remove the DLP pointer and add the
+ LOADED bit flag. Saves 32/64 bytes per file, as this pointer is
+ almost never needed.
+ * read.c (eval): Set the new LOADED bit flag on the file.
+ * file.c (rehash_file): Merge the loaded bitfield.
+ * commands.c (execute_file_commands): Call unload_file() instead
+ of dlclose() directly.
+
+2013-05-14 Paul Smith <psmith@gnu.org>
+
+ * doc/make.texi (Loaded Object API): Document the requirement for
+ the plugin_is_GPL_compatible symbol.

+
+2013-05-13 Paul Smith <psmith@gnu.org>
+
+ * filedef.h (struct file): Add a builtin flag.

+ (rehash_file): Ditto.
+ (print_file): Don't print builtin files if we've omitted them.
+ * default.c (undefine_default_variables): New function: go through
+ the default variables and undefine them.
+ (set_default_suffixes): Mark these suffix rules as builtin.
+ * makeint.h: Prototype.
+ * main.c (main): Handle addition of -r and -R to MAKEFLAGS in the
+ makefile. Fixes Savannah bug #20501.
+
+ * main.c (define_makeflags): Assign o_env_override level to
+ MAKEFLAGS to ensure it's set even in the presence of -e.
+ Fixes Savannah bug #2216.

+
+2013-05-11 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c (child_out): Output the newline following the message
+ before fllush-ing the stream. Avoids displaying the following
+ failure message, which goes to stderr, on the same line.
+
+2013-05-06 Eli Zaretskii <eliz@gnu.org>
+
+ * gnumake.h (GMK_EXPORT) [_WIN32]: Move the dllexport declaration

+ (start_job_command): Move the tmp file assignment earlier. After
+ we do it, write the command line to the temp file to get the order
+ correct.

+ * misc.c (message): Remove special handling for output_sync.
+ (error): Ditto.
+
+2013-05-04 Paul Smith <psmith@gnu.org>

+ handling functions.
+ (Loaded Object Example): Create an example.
+
+ * job.c (pump_from_tmp): (Rename) Write to stdout/stderr using

+2013-05-04 Eli Zaretskii <eliz@gnu.org>
+
+ * makeint.h (ftruncate) [_MSC_VER]: Redirect to _chsize.

+ dumped immediately before starting the child.
+
+2013-05-04 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c (start_job_command): Make the condition for creating a
+ temporary output file be identical to the Posix code branch.
+ Suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>.
+
+2013-05-03 Eli Zaretskii <eliz@gnu.org>
+
+ * w32/subproc/sub_proc.c: Include makeint.h. Remove a private
+ incompatible prototype of xmalloc.
+ (batch_file_with_spaces): New function, detects Windows batch
+ files whose names include whitespace characters.
+ (process_begin): If exec_name is a batch file with whitespace
+ characters in its name, pass NULL as the first argument to
+ CreateProcess. This avoids weird failures due to buggy quoting by
+ CreateProcess. For the details, see the discussion starting at
+ http://lists.gnu.org/archive/html/make-w32/2013-04/msg00008.html.
+

+ decorations for Windows and to nothing on other platforms.
+ (gmk_eval, gmk_expand, gmk_add_function): Add GMK_EXPORT qualifier
+ to prototypes.
+
+ * makeint.h (MAIN): Define before including gnumake.h, to give
+ correct dllexport decorations to exported functions.
+ (load_file): Adjust prototype.
+
+ * loadapi.c: Don't include gnumake.h, since makeint.h already
+ includes it, and takes care of defining MAIN before doing so.
+
+ * build_w32.bat (LinkGCC): Produce an import library for functions
+ exported by Make for loadable dynamic objects.
+
+ * w32/compat/posixfcn.c (dlclose): New function.

+ * job.c (start_job_command) [WINDOWS32]: Make the same fix for
+ MS-Windows as the previous commit did for Posix platforms.
+ (construct_command_argv_internal): Don't treat a backslash as an
+ escape character before whitespace, if the shell is not a Posix

+2013-04-30 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ build: enable the 'silent-rules' automake options
+
+ * configure.ac (AM_INIT_AUTOMAKE): Here. The future major Automake
+ version 2.0 (ETA about one, one and half year from now) will enable
+ it by default, so better prepare ourselves.
+
+2013-04-30 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ build: require Autoconf >= 2.62 and Automake >= 1.11.1
+
+ Older versions of those tools should be considered fully obsolete.
+ Also, GNU make already requires Gettext >= 0.18.1, which has been
+ released six months after Automake 1.11.1 and two years after
+ Autoconf 2.62; so the new requirement shouldn't be problematic
+ for people already bootstrapping GNU make from the Git repository.
+
+ * configure.ac (AC_PREREQ): Require Autoconf 2.62 or later.
+ (AM_INIT_AUTOMAKE): Require Automake 1.11.1 or later (1.11 had
+ some serious bugs, and should not be used).
+
+2013-04-30 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ build: get rid of 'HAVE_ANSI_COMPILER' C preprocessor conditional
+

+ that preprocessor conditional was no longer used anyway.
+
+ * configure.ac: Remove AC_DEFINE of HAVE_ANSI_COMPILER.
+ * config.ami.template: Remove #define of HAVE_ANSI_COMPILER.
+ * config.h-vms.template: Likewise.
+ * config.h.W32.template: Likewise.

+
+2013-04-28 Eli Zaretskii <eliz@gnu.org>
+
+ * dir.c (local_stat) [WINDOWS32]: Use the wrapper on MS-Windows.
+ If the argument ends in "dir/.", make sure the parent dir exists
+ and is indeed a directory. Fixes Savannah bug #37065.
+
+2013-04-28 Paul Smith <psmith@gnu.org>
+
+ * makeint.h (message_s, error_s): Functions that print to strings
+ rather than directly to files.
+ * misc.c (message_s, error_s): Create them.
+ * job.c (child_error): Print error messages to the output sync
+ logs, if one exists, rather then directly to the terminal.
+ (reap_children): Move the per-line sync after child_error().
+
+ * configure.ac: Remove support for pre-ANSI variadic function calls.
+ * makeint.h: Ditto.
+ * misc.c: Ditto.
+ * config.ami.template: Ditto.
+ * config.h-vms.template: Ditto.

+ * job.h (struct child): Avoid ifdefs.
+ * make.1: Add new options to the man page.
+ * doc/make.texi (Parallel Output): Break documentation on input
+ and output into separate sections for readability. Document the
+ new "job" and "none" modes.
+
+2013-04-27 Paul Smith <psmith@gnu.org>
+
+ * job.c (construct_command_argv_internal): Fix oneshell support
+ for non-POSIX-sh shells.
+
+ * load.c (load_object): Extract all POSIX-isms into a separate
+ function for portability.
+ (load_file): Check the .LOADED variable first and don't invoke
+ load_object() if it's already been loaded.
+
+2013-04-27 Eli Zaretskii <eliz@gnu.org>
+
+ * read.c (record_files): Pay attention to .ONESHELL in MS-Windows.
+
+ * job.c (construct_command_argv_internal): Support .ONESHELL on
+ MS-Windows, when the shell is not a Unixy shell.
+
+2013-04-27 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c: Fix compilation error on GNU/Linux due to "label at end
+ of compound statement".
+
+2013-04-27 Frank Heckenbach <f.heckenbach@fh-soft.de> (tiny change)
+
+ * job.c (sync_output): Don't discard the output if
+ acquire_semaphore fails; instead, dump the output unsynchronized.
+
+2013-04-27 Eli Zaretskii <eliz@gnu.org>
+
+ Support --output-sync on MS-Windows.
+ * w32/compat/posixfcn.c: New file, with emulations of Posix
+ functions and Posix functionality for MS-Windows.
+
+ * w32/subproc/sub_proc.c: Include io.h.
+ (process_noinherit): New function, forces a file descriptor to not
+ be inherited by child processes.
+ (process_easy): Accept two additional arguments, and use them to
+ set up the standard output and standard error handles of the child
+ process.
+
+ * w32/include/sub_proc.h (process_easy): Adjust prototype.
+ (process_noinherit): Add prototype.
+
+ * read.c [WINDOWS32]: Include windows.h and sub_proc.h.
+
+ * makeint.h (LOCALEDIR) [WINDOWS32}: Define to NULL if not
+ defined. This is needed because the MS-Windows build doesn't have
+ a canonical place for LOCALEDIR.
+ (WIN32_LEAN_AND_MEAN) [WINDOWS32]: Define, to avoid getting from
+ windows.h header too much stuff that could conflict with the code.
+
+ * main.c <sync_mutex>: New static variable.
+ <switches>: Add support for "--sync-mutex" switch.
+ (decode_output_sync_flags): Decode the --sync-mutex= switch.
+ (prepare_mutex_handle_string) [WINDOWS32]: New function.
+ (main): Add "output-sync" to .FEATURES.

+ (sync_handle_t): New typedef.
+
+ * job.c <sync_handle>: Change type to sync_handle_t.
+ (FD_NOT_EMPTY): Seek to the file's end. Suggested by Frank
+ Heckenbach <f.heckenbach@fh-soft.de>.
+ (pump_from_tmp_fd) [WINDOWS32]: Switch to_fd to binary mode for
+ the duration of this function, and then change back before
+ returning.
+ (start_job_command) [WINDOWS32]: Support output_sync mode on
+ MS-Windows. Use a system-wide mutex instead of locking
+ stdout/stderr. Call process_easy with two additional arguments:
+ child->outfd and child->errfd.
+ (exec_command) [WINDOWS32]: Pass two additional arguments, both
+ -1, to process_easy, to adjust for the changed function signature.
+
+ * function.c (windows32_openpipe) [WINDOWS32]: This function now
+ returns an int, which is -1 if it fails and zero otherwise. It
+ also calls 'error' instead of 'fatal', to avoid exiting
+ prematurely.
+ (func_shell_base) [WINDOWS32]: Call perror_with_name if
+ windows32_openpipe fails, now that it always returns. This avoids
+ a compiler warning that error_prefix is not used in the MS-Windows
+ build.
+
+ * config.h.W32.template (OUTPUT_SYNC): Define.
+
+ * build_w32.bat: Add w32/compat/posixfcn.c to compilation and
+ linking commands.
+
+2013-04-20 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ * README.git: Our autoconf input file is 'configure.ac', not
+ 'configure.in'. Adjust accordingly.
+ * build_w32.bat: Likewise.
+ * config.h-vms.template: Likewise.
+ * Makefile.DOS.template: Likewise.
+
+2013-04-16 Paul Smith <psmith@gnu.org>
+
+ * misc.c (open_tmpfd): Add a new function that returns a temporary
+ file by file descriptor.
+ (open_tmpfile): Move here from main.c.

+ option and its argument.
+
+2013-04-06 Paul Smith <psmith@gnu.org>
+
+ * doc/make.texi (Implicit Variables): Clarify LDFLAGS vs. LDLIBS.
+ Fixes Savannah bug #37970.
+

+ as they may have finished. Fixes Savannah bug #37703.
+
+2013-02-28 Paul Smith <psmith@gnu.org>
+
+ * function.c (func_realpath): On Solaris (at least) realpath() can
+ fail due to EINTR, so loop it. Fixes Savannah bug #38420.
+
+2013-02-25 Paul Smith <psmith@gnu.org>
+
+ Add a proposed supported API for GNU make loaded objects.
+
+ * doc/make.texi (Loaded Object API): Document it.

+
+2013-01-19 Paul Smith <psmith@gnu.org>
+
+ * doc/make.texi (load Directive): Update to discuss location of
+ loaded object file.
+ (Remaking Loaded Objects): Document remaking of loaded objects.
+
+ * main.c (main): Rename READ_MAKEFILES to READ_FILES.
+ * read.c: Change READ_MAKEFILES to READ_FILES since it now
+ contains loaded object files as well.
+ (read_all_makefiles): Ditto.
+ (eval_makefile): Ditto.
+ (eval): Add any loaded file to the READ_FILES list, so that it
+ will be considered for re-build.
+
+ * load.c (load_file): Return the simple filename (no symbol) in
+ the LDNAME argument (now a const char **).
+ This filename should no longer have "./" prepended: modify the
+ function to always check the current directory if the name has no
+ "/", before using the normal methods.
+ * make.h: Change the load_file() prototype.
+
+ * README.git: Add a bit more documentation on Git workflow & rules.
+
+2013-01-13 Paul Smith <psmith@gnu.org>

+ counter of batch files before trying to use it.
+
+2012-12-07 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c (construct_command_argv_internal): Remove " from
+ sh_chars_dos[]. Ignore an escaped backslash inside a string
+ quoted with "..". This lifts the 4KB or 8KB command-line length
+ limitation imposed by the Windows shells when a command uses quoted
+ strings, because we now don't call the shell in that case.
+
+ * job.c (create_batch_file): Declare the counter of batch files
+ static, to avoid having 2 jobs using the same file name and
+ stepping on each other's toes. When all 64K names are used up,
+ make one more loop looking for slots that became vacant. This
+ avoids leaving behind temporary batch files in the temporary
+ directory, which happens frequently on a fast machine when using
+ parallel builds.
+ (reap_children): Add debug message for when removal of a temporary
+ batch file fails.

+ * configure.in (bsd_signal): Define _GNU_SOURCE, a la make.h.
+ Fixes Savannah bug #32247.
+
+ * remake.c (update_file_1): Force intermediate files to be

+ on the heap for very long lines. Fixes Savannah bug #36451.
+
+ * function.c (func_realpath): BSD realpath(3) doesn't fail if the
+ file does not exist: use stat. Fixes Savannah bug #35919.
+
+ * file.c (expand_deps): Duplicate the current variable buffer, not
+ the old pointer. Fixes Savannah bug #36925.
+
+ * read.c (eval): If we detect an initial UTF-8 BOM, skip it.
+ Fixes Savannah bug #36529.
+ (record_target_var): Remove unused variable "fname".
+ (eval): Use the correct pointer when adding to the variable buffer.
+ Fixes Savannah bug #36106.
+

+ * default.c (default_variables): Use a correct default LIBPPATERNS
+ for MacOS. Fixes Savannah bug #37197.
+
+ * read.c (record_files): Reset the default macro values if .POSIX
+ is set. Fixes Savannah bug #37069.
+ (parse_file_seq): Break out of an infinite loop if we're not
+ making progress when parsing archive references.
+
+2012-09-01 Eli Zaretskii <eliz@gnu.org>
+
+ * README.W32.template: Update for job-server and Guile support.
+
+ * read.c (unescape_char): Advance 'p' after copying the unescaped
+ characters. Otherwise the backslashes are incorrectly erased from
+ the original string.
+
+2012-03-05 Paul Smith <psmith@gnu.org>
+
+ Update copyright notices to use year ranges, as allowed by
+ clarifications in the GNU Maintainer's Manual.
+
+2012-03-04 Paul Smith <psmith@gnu.org>
+
+ * read.c (unescape_char): New function to remove escapes from a char.

+2012-03-03 Paul Smith <psmith@gnu.org>
+
+ * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add support for AIX 5.2+

+
+ * configh.dos.template: Remove unconditional definition of

+ Include <sys/version.h> because ports of GCC 4.3.0 and later no

+
+ * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
+ corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
+ instead of using the hardcoded ones.
+ (SUBDIRS): doc subdir added.
+ (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.

+
+2009-09-24 Paul Smith <psmith@gnu.org>
+
+ * implicit.c (pattern_search): Add back support for order-only

+ sure to either save or free them as appropriate.
+
+2009-09-23 Paul Smith <psmith@gnu.org>
+
+ Rework the way secondary expansion is stored, for efficiency.
+ This changes secondary expansion so that ONLY WHEN we know we have
+ a possibility of needing secondary expansion, do we defer the
+ secondary expansion. This means more parsing the deps but we use
+ a lot less memory (due to the strcache). Also, this fixes
+ Savannah bug #18622.
+
+ * read.c (eval): Don't parse the dep string here anymore.
+ (record_files): Take the dep argument as an unparsed string. If
+ secondary expansion is enabled AND the prereq string has a '$' in
+ it, then set NEED_2ND_EXPANSION and keep the entire string.
+ Otherwise, parse the dep string here to construct the dep list
+ with the names in the strcache.
+
+ * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
+ duplicate the name string (others are in the strcache).
+
+ * implicit.c: Remove struct idep and free_idep_chain(): unused.
+ (struct patdeps): New structure to store prereq information.
+ (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
+ which prerequisites need expansion, and expand only those.
+
+ * file.c (split_prereqs): Break parse_prereqs() into two parts: this
+ and enter_prereqs(). split_prereqs() takes a fully-expanded string
+ and splits it into a DEP list, handling order-only prereqs.
+ (enter_prereqs): This function enters a list of DEPs into the file
+ database. If there's a stem defined, expand any pattern chars.
+ (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
+ set. Use the above functions.
+ (snap_deps): Only perform second expansion on prereqs that need it,
+ as defined by the NEED_2ND_EXPANSION flag.
+ (print_prereqs): New function to print the prereqs
+ (print_file): Call print_prereqs() rather than print inline.
+
+ * hash.h (STRING_COMPARE): Take advantage of strcache() by
+ comparing pointers.
+ (STRING_N_COMPARE): Ditto.

+ * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
+ all. Avoid reversing chains. Support adding prefixes.
+ * read.c (parse_file_seq): Rewrite to support globbing. Allow for

+ target/prereq relationships during snap_deps.
+ Fixes Savannah bug #24622.
+
+ * read.c (record_files): The second-expansion "f->updating" hack
+ was not completely correct: if assumed that the target with
+ commands always had prerequisites; if one didn't then the ordering
+ was messed up. Fixed for now to use f->updating to decide whether
+ to preserve the last element in the deps list... but this whole

+ * job.c (start_job_command): Reset the stack limit, if we changed it.
+ Fixes Savannah bug #22010.
+
+ * remake.c (check_dep): Only set the target's state to not-started
+ if it's not already running. Found this while testing -j10 builds
+ of glibc: various targets were being rebuilt multiple times.
+ Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
+ bug #15919.
+
+ * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead

+
+2009-06-02 Paul Smith <psmith@gnu.org>
+
+ * configure.in: Check for fileno()
+ * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC

+ Fixes Savannah bug #24277.
+
+2009-06-01 Paul Smith <psmith@gnu.org>
+
+ * main.c (main): The previous fix for .DEFAULT_GOAL had issues;

+
+2009-05-31 Paul Smith <psmith@gnu.org>

+ Fixes Savannah bug #25712.
+
+ * implicit.c (pattern_search): Keep a pointer to the beginning of

+ Fixes Savannah bug #25412.
+
+ * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
+ prototype for xmalloc.
+ (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
+ instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
+ Loop over an array of extensions, instead of duplicating the same
+ code inline. Use SearchPath followed by CreateFile, instead of
+ the obsolete OpenFile. Fixes Savannah bug #17277.
+ (process_begin): Find $(PATH) in `envp', and pass a pointer to it
+ to `find_file'. Fixes Savannah bug #25662.

+
+2007-10-12 Eli Zaretskii <eliz@gnu.org>
+
+ * variable.c (do_variable_definition): Allow $(SHELL) to expand to

+ (Error Messages): Ditto.
+
+2007-09-10 Paul Smith <psmith@gnu.org>

+
+2007-08-15 Paul Smith <psmith@gnu.org>
+

+
+2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>

+
+2007-05-08 Paul Smith <psmith@gnu.org>
+
+ Fix Savannah bug #19656:
+
+ * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
+
+ * make.h: Change all case-insensitive string compares to use
+ strcasecmp() (from POSIX). If we don't have that but do have one
+ of the others, define strcasecmp to be one of those instead. If
+ we don't have any, declare a prototype for our own version.
+
+ * misc.c (strcasecmp): Use this if we can't find any native
+ case-insensitive string comparison function.
+ * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
+ * main.c (find_and_set_default_shell): Use strcasecmp() instead of
+ strcmpi().
+ * job.c (_is_unixy_shell, construct_command_argv_internal): Use
+ strcasecmp() instead of stricmp().
+ * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
+ instead of strcmpi().
+ * acinclude.m4: Remove the strcasecmp() check from here.
+
+2007-03-21 Paul Smith <psmith@gnu.org>
+
+ * configure.in: Don't turn on case-insensitive file system support
+ if --disable-... is given. Fixes Savannah bug #19348.
+
+2007-03-19 Paul Smith <psmith@gnu.org>
+
+ * ALL: Use the strcache for all file name strings, or other
+ strings which we will never free. The goal is to save memory by
+ avoiding duplicate copies of strings. However, at the moment this
+ doesn't save much memory in most situations: due to secondary
+ expansion we actually save prerequisite lists twice (once before
+ the secondary expansion, and then again after it's been parsed
+ into individual file names in the dep list). We will resolve this
+ in a future change, by doing the parsing up-front for targets
+ where secondary expansion is not set.
+
+ Moving things into the strcache also allows us to use const
+ pointers in many more places.
+
+2007-01-03 Paul Smith <psmith@gnu.org>
+
+ * make.h (ENULLLOOP): Reset errno after each failed invocation of
+ the function, not just the first. Fixes Savannah bug #18680.
+
+2006-11-18 Paul Smith <psmith@gnu.org>
+
+ * strcache.c (strcache_add_len): Don't allocate a new buffer
+ unless the string is not already nil-terminated. Technically this
+ is a violation of the standard, since we may be passed an array
+ that is not long enough to test one past. However, in make this
+ is never true since we only use nil-terminated strings or
+ sub-strings thereof.
+
+ * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
+
+ * main.c: New global cmd_prefix, defaults to '\t'.
+ * job.c (construct_command_argv_internal): Use cmd_prefix instead
+ of '\t'.
+
+ * dir.c: Constified.

+2006-03-25 Eli Zaretskii <eliz@gnu.org>
+

+
+ * main.c (clean_jobserver): Move jobserver cleanup code into a new

+ Fixes Savannah bug #15913.
+
+2006-03-09 Paul Smith <psmith@gnu.org>
+
+ * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
+ listed non-existent files as changed. Turns out there's a bug in

+ Fixes Savannah bug #16002.
+ Introduces Savannah bug #16051.

+
+ * commands.c (set_file_variables): Realloc, not malloc, the static
+ string values to avoid memory leaks.
+
+ * expand.c (recursively_expand_for_file): Only set reading_file to
+ an initialized value.
+
+ * implicit.c (pattern_search): We need to make a copy of the stem

+
+2006-02-17 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (merge_variable_set_lists): Don't try to merge the
+ global_setlist. Not only is this useless, but it can lead to
+ circularities in the linked list, if global_setlist->next in one
+ list gets set to point to another list which also ends in
+ global_setlist.
+ Fixes Savannah bug #15757.
+
+2006-02-15 Paul D. Smith <psmith@gnu.org>
+
+ Fix for Savannah bug #106.
+
+ * expand.c (expanding_var): Keep track of which variable we're
+ expanding. If no variable is being expanded, it's the same as
+ reading_file.
+ * make.h (expanding_var): Declare it.
+ * expand.c (recursively_expand_for_file): Set expanding_var to the
+ current variable we're expanding, unless there's no file info in

+ * variable.c (free_variable_set): New function.

+ * (ALL FILES): Updated copyright and license notices.
+
+2006-02-10 Paul D. Smith <psmith@gnu.org>
+
+ A new internal capability: the string cache is a read-only cache
+ of strings, with a hash table interface for fast lookup. Nothing
+ in the cache will ever be freed, so there's no need for reference
+ counting, etc. This is the beginning of a full solution for
+ Savannah bug #15182, but for now we only store makefile names here.
+
+ * strcache.c: New file. Implement a read-only string cache.
+ * make.h: Add prototypes for new functions.
+ * main.c (initialize_global_hash_tables): Initialize the string cache.

+ Fixes Savannah bug #15533.
+ * filedef.h (struct file): Add a new LAST pointer.

+
+2006-01-21 Eli Zaretskii <eliz@gnu.org>
+
+ * remake.c (update_goal_chain): Set g->changed instead of

+ many commands got started in update_file.
+

+ From Martin Zinser <zinser@zinser.no-ip.info>
+
+2005-07-03 Paul D. Smith <psmith@gnu.org>
+
+ From J. Grant <jg@jguk.org>:

+
+2005-06-27 Paul D. Smith <psmith@gnu.org>
+
+ * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
+ to unsigned long. Fixes Savannah bug #13550.
+
+ * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.

+
+2005-06-25 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (eval): If no filenames are passed to any of the
+ "include" variants, don't print an error.
+ * doc/make.texi (Include): Document this.
+ Fixes Savannah bug #1761.
+
+ * job.c (construct_command_argv_internal): Sanitize handling of
+ backslash/newline pairs according to POSIX: that is, keep the
+ backslash-newline in the command script, but remove a following
+ TAB character, if present. In the fast path, make sure that the
+ behavior matches what the shell would do both inside and outside
+ of quotes. In the slow path, quote the backslash and put a
+ literal newline in the string.
+ Fixes Savannah bug #1332.
+ * doc/make.texi (Execution): Document the new behavior and give
+ some examples.
+ * NEWS: Make a note of the new behavior.
+
+ * make.h [WINDOWS32]: #include <direct.h>.
+ Fixes Savannah bug #13478.
+
+ * remake.c (name_mtime): If the stat() of a file fails and the -L
+ option was given and the file is a symlink, take the best mtime of
+ the symlink we can get as the mtime of the file and don't fail.
+ Fixes Savannah bug #13280.
+
+ * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
+ If it's set, then don't stop on STOPCHARs or BLANKs if they're
+ inside a variable reference. Make this function static as it's
+ only used here.
+ (eval): Call find_char_unquote() with IGNOREVARS set when we're
+ parsing an unexpanded line looking for semicolons.
+ Fixes Savannah bug #1454.
+ * misc.c (remove_comments): Move this to read.c and make it static
+ as it's only used there. Call find_char_unquote() with new arg.
+ * make.h: Remove prototypes for find_char_unquote() and
+ remove_comments() since they're static now.
+
+ * main.c (main): If we see MAKE_RESTARTS in the environment, unset
+ its export flag and obtain its value. When we need to re-exec,
+ increment the value and add it into the environment.
+ * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
+ * NEWS: Mention MAKE_RESTARTS.
+ * main.c (always_make_set): New variable. Change the -B option to
+ set this one instead.
+ (main): When checking makefiles, only set always_make_flag if
+ always_make_set is set AND the restarts flag is 0. When building
+ normal targets, set it IFF always_make_set is set.
+ (main): Avoid infinite recursion with -W, too: only set what-if
+ files to NEW before we check makefiles if we've never restarted
+ before. If we have restarted, set what-if files to NEW _after_ we
+ check makefiles.
+ Fixes Savannah bug #7566:

+
+ Fix Savannah bug # 1328.
+
+ * configure.in: Check for atexit().

+ code found in gnulib.
+ * make.h: Prototype.
+ * main.c (main): Install close_stdout() with atexit().
+
+2005-06-10 Paul D. Smith <psmith@gnu.org>
+
+ VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
+
+ * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
+ headers; make vmsWaitForChildren() static; extern vmsify().
+ * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
+ Don't create child_execute_job() here (it's in vmsjobs.c).
+ * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
+
+2005-06-09 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (push_new_variable_scope): File variables point
+ directly to the global_setlist variable. So, inserting a new
+ scope in front of that has no effect on those variables: they
+ don't go through current_variable_set_list. If we're pushing a
+ scope and the current scope is global, push it "the other way" so
+ that the new setlist is in the global_setlist variable, and
+ next points to a new setlist with the global variable set.
+ (pop_variable_scope): Properly undo a push with the new
+ semantics.
+ Fixes Savannah bug #11913.
+
+2005-05-31 Boris Kolpackov <boris@kolpackov.net>
+
+ * job.c (reap_children): Don't die of the command failed but
+ the dontcare flag is set. Fixes Savannah bug #13216.
+
+ * implicit.c (pattern_search): When creating a target from
+ an implicit rule match, lookup pattern target and set precious
+ flag in a newly created target. Fixes Savannah bug #13218.
+
+2005-05-13 Paul D. Smith <psmith@gnu.org>
+
+ Implement "if... else if... endif" syntax.
+
+ * read.c (eval): Push all checks for conditional words ("ifeq",
+ "else", etc.) down into the conditional_line() function.
+ (conditional_line): Rework to allow "else if..." clause. New
+ return value -2 for lines which are not conditionals. The
+ ignoring flag can now also be 2, which means "already parsed a
+ true branch". If that value is seen no other branch of this
+ conditional can be considered true. In the else parsing if there
+ is extra text after the else, invoke conditional_line()
+ recursively to see if it's another conditional. If not, it's an
+ error. If so, raise the conditional value to this level instead
+ of creating a new conditional nesting level. Special check for
+ "else" and "endif", which aren't allowed on the "else" line.
+ * doc/make.texi (Conditional Syntax): Document the new syntax.
+
+2005-05-09 Paul D. Smith <psmith@gnu.org>
+
+ * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
+ (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
+ recurses to the w32 directory, even on non-Windows systems. Use
+ the method suggested in the automake manual.
+ * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
+ * maintMakefile (gnulib-url): They moved the texinfo.tex files.
+
+2005-05-07 Paul D. Smith <psmith@gnu.org>
+
+ * main.c (die): If we're dying with a fatal error (not that a
+ command has failed), write back any leftover tokens before we go.
+
+ * job.c (set_child_handler_action_flags): If there are jobs
+ waiting for the load to go down, set an alarm to go off in 1
+ second. This allows us to wake up from a potentially long-lasting
+ read() and start a new job if the load has gone down. Turn it off
+ after the read.
+ (job_noop): Dummy signal handler function.
+ (new_job): Invoke it with the new semantics.
+
+ * docs/make.texi: Document secondary expansion. Various cleanups
+ and random work.
+
+2005-05-03 Paul D. Smith <psmith@gnu.org>
+
+ Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
+ the targets which are to ultimately be made are called "goals";
+ see the GNU make manual. Also, MAKECMDGOALS, etc.
+
+ * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
+ .DEFAULT_GOAL, and default_target_name to default_goal_name.
+ * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
+
+2005-05-02 Paul D. Smith <psmith@gnu.org>
+
+ * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
+ vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
+ tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
+ functions to vmsjobs.c. #include it into jobs.c.
+
+ Grant Taylor <gtaylor@picante.com> reports that -j# can lose
+ jobserver tokens. I found that this happens when an exported
+ recursive variable contains a $(shell ...) function reference: in
+ this situation we could "forget" to write back a token.
+
+ * job.c, job.h: Add variable jobserver_tokens: counts the tokens
+ we have. It's not reliable to depend on the number of children in
+ our linked list so keep a separate count.
+ (new_job): Check jobserver_tokens rather than children &&
+ waiting_jobs. Increment jobserver_tokens when we get one.
+ (free_child): If jobserver_tokens is 0, internal error. If it's
+ >1, write a token back to the jobserver pipe (we don't write a
+ token for the "free" job). Decrement jobserver_tokens.
+
+ * main.c: Add variable master_job_slots.
+ (main): Set it to hold the number of jobs requested if we're the
+ master process, when using the jobserver.
+ (die): Sanity checks: first test jobserver_tokens to make sure
+ this process isn't holding any tokens we didn't write back.
+ Second, if master_job_slots is set count the tokens left in the
+ jobserver pipe and ensure it's the same as master_job_slots (- 1).
+
+2005-04-24 Paul D. Smith <psmith@gnu.org>
+
+ Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
+ with -l# can lose jobserver tokens, because waiting jobs are not
+ consulted properly when checking for the "free" token.
+
+ * job.c (free_child): Count waiting_jobs as having tokens.
+ * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
+ handle jobs waiting for the load to drop.
+
+2005-04-23 Paul D. Smith <psmith@gnu.org>
+
+ * main.c (main): Be careful to not core if a variable setting in
+ the environment doesn't contain an '='. This is illegal but can
+ happen in broken setups.
+ Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
+
+2005-04-12 Paul D. Smith <psmith@gnu.org>
+
+ The second expansion feature causes significant slowdown. Timing
+ a complex makefile (GCC 4.1) shows a slowdown from .25s to just
+ read the makefile before the feature, to 11+s to do the same
+ operations after the feature. Additionally, memory usage
+ increased drastically. To fix this I added some intelligence that
+ avoids the overhead of the second expansion unless it's required.
+
+ * dep.h: Add a new boolean field, need_2nd_expansion.
+
+ * read.c (eval): When creating the struct dep for the target,
+ check if the name contains a "$"; if so set need_2nd_expansion to 1.
+ (record_files): If there's a "%" in a static pattern rule, it gets
+ converted to "$*" so set need_2nd_expansion to 1.
+
+ * file.c (expand_deps): Rework to be more efficient. Only perform
+ initialize_file_variables(), set_file_variables(), and
+ variable_expand_for_file() if the need_2nd_expansion is set.
+
+ * implicit.c (pattern_search): Default need_2nd_expansion to 0.
+ (pattern_search): Ditto.
+ * main.c (handle_non_switch_argument): Ditto.
+ (main): Ditto.
+ * read.c (read_all_makefiles): Ditto.

+ * main.c (main): Define the .FEATURES variable.
+ * NEWS: Announce .FEATURES.
+ * doc/make.texi (Special Variables): Document .FEATURES.

+ it's marked intermediate. Fixes Savannah bug #12331.
+
+2005-03-15 Boris Kolpackov <boris@kolpackov.net>
+
+ * file.c (expand_deps): Factor out the second expansion and
+ prerequisite line parsing logic from snap_deps().
+
+ * file.c (snap_deps): Use expand_deps(). Expand and parse

+ Savannah bug #12320.
+

+
+2005-03-10 Boris Kolpackov <boris@kolpackov.net>
+
+ * implicit.c (pattern_search): Mark an intermediate target as

+
+2005-03-04 Boris Kolpackov <boris@kolpackov.net>

+
+2005-03-03 Boris Kolpackov <boris@kolpackov.net>
+
+ * read.c (record_files): Instead of substituting % with
+ actual stem value in dependency list replace it with $*.
+ This fixes stem triple expansion bug.
+
+ * implicit.c (pattern_search): Copy stem to a separate
+ buffer and make it a properly terminated string. Assign
+ this buffer instead of STEM (which is not terminated) to
+ f->stem. Instead of substituting % with actual stem value

+ triple expansion bug.
+
+2005-03-01 Paul D. Smith <psmith@gnu.org>
+
+ * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()

+ Fix from patch #3679, provided by Alessandro Vesely.
+
+ * configure.in: Update check for sys_siglist[] from autoconf manual.
+ * signame.c (strsignal): Update to use the new autoconf macro.
+
+2005-03-01 Boris Kolpackov <boris@kolpackov.net>
+
+ * read.c (record_files): Add a check for the list of prerequisites

+
+2005-02-28 Paul D. Smith <psmith@gnu.org>
+
+ * doc/make.texi (Text Functions): Update docs to allow the end
+ ordinal for $(wordlist ...) to be 0.
+ * function.c (func_wordlist): Fail if the start ordinal for
+ $(wordlist ...) is <1. Matches documentation.
+ Resolves Savannah support request #103195.
+
+ * remake.c (update_goal_chain): Fix logic for stopping in -q:
+ previously we were stopping when !-q, exactly the opposite. This
+ has been wrong since version 1.34, in 1994!
+ (update_file): If we got an error don't break out to run more
+ double-colon rules: just return immediately.
+ Fixes Savannah bug #7144.
+

+ (function_table_init): Add new function to the table.
+ * NEWS: Add $(info ...) reference.
+ * doc/make.texi (Make Control Functions): Document it.
+
+ New feature: if the system supports symbolic links, and the user
+ provides the -L/--check-symlink-time flag, then use the latest
+ mtime between the symlink(s) and the target file.
+
+ * configure.in (MAKE_SYMLINKS): Check for lstat() and
+ readlink(). If both are available, define MAKE_SYMLINKS.
+ * main.c: New variable: check_symlink_flag.
+ (usage): Add a line for -L/--check-symlink-times to the help string.
+ (switches): Add -L/--check-symlink-times command line argument.
+ (main): If MAKE_SYMLINKS is not defined but the user specified -L,
+ print a warning and disable it again.
+ * make.h: Declare check_symlink_flag.
+ * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
+ if the file is a symlink then check each link in the chain and
+ choose the NEWEST mtime we find as the mtime for the file. The
+ newest mtime might be the file itself!
+ * NEWS: Add information about this new feature.
+ * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
+
+ Avoid core dumps described in Savannah bug # 12124:
+

+ snap_deps().
+ (snap_deps): Set it.
+ * filedef.h: Extern it.
+ * read.c (record_files): Check snapped_deps; if it's set then

+
+2005-02-27 Boris Kolpackov <boris@kolpackov.net>
+
+ Implementation of the second expansion in explicit rules,
+ static pattern rules and implicit rules.
+
+ * read.c (eval): Refrain from chopping up rule's dependencies.
+ Store them in a struct dep as a single dependency line. Remove
+ the code that implements SySV-style automatic variables.
+
+ * read.c (record_files): Adjust the code that handles static
+ pattern rules to expand all percents instead of only the first
+ one. Reverse the order in which dependencies are stored so that
+ when the second expansion reverses them again they appear in
+ the makefile order (with some exceptions, see comments in
+ the code). Remove the code that implements SySV-style automatic
+ variables.
+
+ * file.c (snap_deps): Implement the second expansion and chopping
+ of dependency lines for explicit rules.
+
+ * implicit.c (struct idep): Define an auxiliary data type to hold

+
+ * implicit.c (free_idep_chain): Implement.
+
+ * implicit.c (get_next_word): Implement helper function for

+
+2005-02-24 Jonathan Grant <jg@jguk.org>
+
+ * configure.in: Add MinGW configuration options, and extra w32 code

+
+2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
+
+ * function.c (func_shell): When initializing error_prefix, check

+
+2005-02-09 Paul D. Smith <psmith@gnu.org>
+
+ * maintMakefile: Update the CVS download URL to simplify them.
+ Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
+ downloading the .texi files from Savannah now.
+
+ Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
+
+ * main.c (handle_non_switch_argument): Only add variables to
+ command_variables if they're not already there: duplicate settings
+ waste space and can be confusing to read.
+
+ * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
+ this header is never included by non-WINDOWS32 code, and it
+ requires <config.h> to define which isn't always included first.
+
+ * dir.c (read_dirstream) [MINGW]: Use proper macro names when
+ testing MINGW32 versions.
+
+ * main.c (log_working_directory): flush stdout to be sure the WD

+
+ * configure.in: The old way we avoided creating build.sh from
+ build.sh.in before build.sh.in exists doesn't work anymore; we
+ have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
+ the help!). This also keeps automake from complaining.
+ * Makefile.am (README): Add a dummy target so automake won't
+ complain that this file doesn't exist when we checkout from CVS.
+ * maintMakefile (.dep_segment): Rewrite this rule since newer
+ versions of automake don't provide DEP_FILES.

+ Fix for bug #1276: Handle SHELL according to POSIX requirements.
+
+ * main.c (main): Set SHELL to v_noexport by default. Remember the
+ original environment setting of SHELL in the env_shell variable.
+ * main.h: Export new env_shell variable.
+ * variable.c (target_environment): If we find a v_noexport
+ variable for SHELL, add a SHELL variable with the env_shell value.
+ * doc/make.texi (Quick Reference): Document the POSIX behavior.
+ * doc/make.texi (Variables/Recursion): Ditto.
+
+2004-11-28 Paul D. Smith <psmith@gnu.org>
+
+ * main.c (find_and_set_default_shell) [WINDOWS32]: check for
+ equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
+ Patch by Alessandro Vesely.
+
+2004-11-12 Paul D. Smith <psmith@gnu.org>
+
+ * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
+ the command line if it's inside a string.
+ Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
+
+2004-10-21 Boris Kolpackov <boris@kolpackov.net>
+
+ * function.c (func_lastword): New function: return last word
+ from the list of words.
+ * doc/make.texi: Document $(lastword ). Fix broken links in
+ Quick Reference section.
+
+2004-10-06 Paul D. Smith <psmith@gnu.org>
+
+ Apply patch from Alessandro Vesely, provided with bug # 9748.
+ Fix use of tmpnam() to work with Borland C.
+
+ * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
+ construction of a temporary filename, and call new function
+ create_batch_filename().
+ (create_batch_filename) [WINDOWS32]: New function to create a
+ temporary filename.
+
+2004-10-05 Boris Kolpackov <boris@kolpackov.net>
+
+ * read.c (record_target_var): Expand simple pattern-specific
+ variable.
+ * variable.c (initialize_file_variables): Do not expand simple
+ pattern-specific variable.
+
+2004-09-28 Boris Kolpackov <boris@kolpackov.net>
+
+ * remake.c (update_file_1): When rebuilding makefiles inherit
+ dontcare flag from a target that triggered update.
+
+2004-09-27 Boris Kolpackov <boris@kolpackov.net>
+
+ * variable.c (initialize_file_variables): Mark pattern-specific
+ variable as a per-target and copy export status.
+
+2004-09-21 Boris Kolpackov <boris@kolpackov.net>
+
+ * file.c (snap_deps): Mark .PHONY prerequisites as targets.
+
+ * implicit.c (pattern_search): When considering an implicit rule's
+ prerequisite check that it is actually a target rather then
+ just an entry in the file hashtable.
+
+2004-09-21 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (readstring): Fix some logic errors in backslash handling.
+ (eval): Remove some unnecessary processing in buffer handling.
+ (record_target_var): Assert that parse_variable_definition() succeeded.
+ Reported by: Markus Mauhart <qwe123@chello.at>.
+
+ * misc.c: Removed the sindex() function. All instances of this
+ function were trivially replaceable by the standard strstr()
+ function, and that function will always have better (or certainly
+ no worse) performance than the very simple-minded algorithm
+ sindex() used. This can matter with complex makefiles.
+ * make.h: Remove the prototype for sindex().
+ * function.c (subst_expand): Convert sindex() call to strstr().
+ This means we no longer need to track the TLEN value so remove that.
+ (func_findstring): Convert sindex() to strstr().
+ * commands.c (chop_commands): Convert sindex() calls to strstr().
+ Suggested by: Markus Mauhart <qwe123@chello.at>.
+
+ * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
+ idea behind Savannah Patch #3144 from david.baird@homemail.com.
+ If SHELL is set to CMD.EXE then assume it's batch-mode and
+ non-unixy. I wrote the code differently from the patch, though,
+ to make it safer. This also resolves bug #9174.
+
+2004-09-20 Paul D. Smith <psmith@gnu.org>
+
+ * expand.c (variable_expand_string): Modify to invoke
+ patsubst_expand() instead of subst_expand(); the latter didn't
+ handle suffix patterns correctly.
+ * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
+ was used only from variable_expand_string() and is no longer used
+ there.
+ (func_subst): Ditto, on call to subst_expand().
+ (patsubst_expand): Require the percent pointers to point to the
+ character after the %, not to the % itself.
+ * read.c (record_files): New call criteria for patsubst_expand().
+ * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
+ This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
+
+2004-09-19 Paul D. Smith <psmith@gnu.org>
+
+ * function.c (subst_expand): Fix a check in by_word: look for a
+ previous blank if we're beyond the beginning of the string, not
+ the beginning of the word.
+ Bugs reported by Markus Mauhart <qwe123@chello.at>.
+
+2004-05-16 Paul D. Smith <psmith@gnu.org>
+
+ * remake.c (update_goal_chain): Change the argument specifying
+ whether we're rebuilding makefiles to be a global variable,
+ REBUILDING_MAKEFILES.
+ (complain): Extract the code that complains about no rules to make
+ a target into a separate function.
+ (update_file_1): If we tried to rebuild a file during the makefile
+ rebuild phase and it was dontcare, then no message was printed.
+ If we then try to build the same file during the normal build,
+ print a message this time.
+ (remake_file): Don't complain about un-remake-able files when
+ we're rebuilding makefiles.
+
+2004-05-11 Paul D. Smith <psmith@gnu.org>
+
+ * job.c (construct_command_argv_internal): OS/2 patches from
+ Andreas Buening <andreas.buening@nexgo.de>.
+
+2004-05-10 Paul D. Smith <psmith@gnu.org>
+
+ * remake.c (update_file): Don't walk the double-colon chain unless
+ this is a double-colon rule. Fix suggested by Boris Kolpackov
+ <boris@kolpackov.net>.
+
+ * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
+ * readme.vms: New section describing OpenVMS support and issues.
+ * default.c (default_variables): Add support for IA64.
+ * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
+ without some privilege aborts make with the error
+ %SYSTEM-F-NOPRIV. It happens when setting up a handler for
+ pressing Ctrl+Y and the input device is no terminal. The change
+ catches this error and just continues.
+
+ Patches by Hartmut Becker <Hartmut.Becker@hp.com>
+
+2004-04-25 Paul D. Smith <psmith@gnu.org>
+
+ * commands.c (set_file_variables): Set $< properly in the face of
+ order-only prerequisites.
+ Patch from Boris Kolpackov <boris@kolpackov.net>
+
+2004-04-21 Bob Byrnes <byrnes@curl.com>
+
+ * main.c (main): Notice failures to remake makefiles.
+
+2004-03-28 Paul D. Smith <psmith@gnu.org>
+
+ Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
+
+ * job.c: No default shell for RISC OS.
+ (load_too_high): Hard-code the return to 1.
+ (construct_command_argv_internal): No sh_chars or sh_cmds.
+ * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
+
+2004-03-20 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (do_variable_definition): Don't append from the
+ global set if a previous non-appending target-specific variable
+ definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
+ (with fix).
+
+ * expand.c (reference_variable): Don't give up on variables with
+ no value that have the target-specific append flag set: they might
+ have a value after all. Reported by Oliver Schmidt
+ <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
+ <nikulin@dx1cmd.inp.nsk.su>.
+
+ * rule.c (count_implicit_rule_limits): Don't delete patterns which
+ refer to absolute pathnames in directories that don't exist: some
+ portion of the makefile could create those directories before we
+ match the pattern. Fixes bugs #775 and #108.
+
+ Fixes from Jonathan R. Grant <jg-make@jguk.org>:
+
+ * main.c (main): Free makefile_mtimes if we have any.
+ * README.W32.template: Update documentation for the current status
+ of the MS-Windows port.
+ * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
+ environment variable is sometimes already defined which causes the
+ build to fail.
+ * main.c (debug_signal_handler): Only define this function if
+ SIGUSR1 is available.
+
+ Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
+
+ * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
+ * README.OS2.template: Documentation updates.
+ * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
+ link line for safety.
+ * maintMakefile (build.sh.in): Remove an extraneous ")".
+ * job.c (child_execute_job): Close saved FDs.
+ * job.c (exec_command) [OS/2]: exec_command(): If the command
+ can't be exec'ed and if the shell is not Unix-sh, then try again
+ with argv = { "cmd", "/c", ... }. Normally, this code is never
+ reached for the cmd shell unless the command really doesn't exist.
+ (construct_command_argv_internal) [OS/2]: The code for cmd
+ handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
+ The CMD builtin commands are case insensitive so use strcasecmp().
+
+2004-03-19 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (do_define): Re-order line counter increment so the count
+ is accurate (we were losing one line per define). Reported by
+ Dave Yost <Dave@Yost.com>.
+
+2004-03-06 Paul D. Smith <psmith@gnu.org>
+
+ * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
+ compiler.

+
+2004-03-04 Paul D. Smith <psmith@gnu.org>
+
+ * README.template: Add a note about broken /bin/sh on SunOS
+ 4.1.3_U1 & 4.1.4. Fix up Savannah links.
+
+ * misc.c (message, error, fatal): Don't use "..." if we're using
+ varargs. ansi2knr should handle this but it doesn't work: it
+ translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
+ done. On many systems (SunOS for example) va_dcl is a #define.
+ So, force the use of the non-"..." version on pre-ANSI compilers.
+
+ * maintMakefile (sign-dist): Create some rules to help automate
+ the new GNU ftp upload method.
+
+2004-02-24 Paul D. Smith <psmith@gnu.org>
+
+ * config.h.W32.template: Add HAVE_STDARG_H
+ * config.h-vms.template: Ditto.
+ * config.ami.template: Ditto.
+
+2004-02-23 Jonathan Grant <jg-make@jguk.org>
+
+ * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
+ * build_w32.bat: Remove extra "+".
+
+2004-02-23 Paul D. Smith <psmith@gnu.org>
+
+ * make.h: Create an UNUSED macro to mark unused parameters.
+ * (many): Clean up warnings by applying UNUSED, fixing
+ signed/unsigned incompatibilities, etc.
+
+ * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
+ autoconf warnings.
+ * filedef.h: Name the command_state enumeration.
+ * file.c (set_command_state): Use the enumeration in the function
+ argument.
+
+ * configure.in: Explicitly set SET_MAKE to empty, to disable
+ MAKE=make even when no make already exists. Fix bug #3823.
+
+2004-02-22 Paul D. Smith <psmith@gnu.org>
+
+ * maintMakefile: Perl script to clean up all non-CVS files. Use
+ it on all the subdirectories for the cvs-clean target.
+
+ * main.c (decode_switches): Require non-empty strings for all our
+ string command-line options. Fixes Debian bug # 164165.
+
+ * configure.in: Check for stdarg.h and varargs.h.
+ * make.h (USE_VARIADIC): Set this if we can use variadic functions
+ for printing messages.
+ * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
+ (message): Ditto.
+ (error): Ditto.
+ (fatal): Ditto.
+
+ A number of patches for OS/2 support from Andreas Buening
+ <andreas.buening@nexgo.de>:
+
+ * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
+ disable the SIGCHLD handler.
+ (reap_children) [OS/2]: Remove special handling of job_rfd.
+ (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
+ (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
+ * main.c (main) [OS/2]: Special handling for paths in OS/2.
+ * configure.in [OS/2]: Force SA_RESTART for OS/2.
+ * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
+ systems.
+
+2004-02-21 Paul D. Smith <psmith@gnu.org>
+
+ * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
+ <mail@kristov.de> reports that if process_begin() fails we don't
+ handle the error condition correctly in all cases.
+ * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
+ to have a newline on the message.
+
+ * job.c (construct_command_argv_internal): Add "test" to UNIX
+ sh_cmds[]. Fixes Savannah bug # 7606.
+
+2004-02-04 Paul D. Smith <psmith@gnu.org>
+
+ * job.c (vms_handle_apos) [VMS]: Fix various string handling
+ situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
+ Hartmut Becker <Hartmut.Becker@hp.com>.
+
+2004-01-21 Paul D. Smith <psmith@gnu.org>
+
+ * job.c (load_too_high): Implement an algorithm to control the
+ "thundering herd" problem when using -l to control job creation
+ via the load average. The system only recomputes the load once a
+ second but we can start many jobs in a second. To solve this we
+ keep track of the number of jobs started in the last second and
+ apply a weight to try to guess what a correct load would be.
+ The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
+ Also fixes bug #4693.
+ (reap_children): Decrease the job count for this second.
+ (start_job_command): Increase the job count for this second.
+
+ * read.c (conditional_line): Expand the text after ifn?def before
+ checking to see if it's a single word. Fixes bug #7257.
+
+2004-01-09 Paul D. Smith <psmith@gnu.org>
+
+ * file.c (print_file): Recurse to print all targets in

+ Andrew Chatham <chatham@google.com>.
+
+2004-01-07 Paul D. Smith <psmith@gnu.org>

+ * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
+ * configure.in: Change make_FUNC_SETVBUF_REVERSED to
+ AC_FUNC_SETVBUF_REVERSED.
+
+ * doc/make.texi (Target-specific): Fix Savannah bug #1772.
+ (MAKE Variable): Fix Savannah bug #4898.
+
+ * job.c (construct_command_argv_internal): Add "!" to the list of
+ shell escape chars. POSIX sh allows it to appear before a
+ command, to negate the exit code. Fixes bug #6404.
+
+ * implicit.c (pattern_search): When matching an implicit rule,
+ remember which dependencies have the ignore_mtime flag set.
+ Original fix provided in Savannah patch #2349, by Benoit
+ Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
+
+2003-11-22 Paul D. Smith <psmith@gnu.org>

+ <jg-make@jguk.org>.
+
+2003-11-02 Paul D. Smith <psmith@gnu.org>
+
+ * function.c (func_if): Strip all the trailing whitespace from the
+ condition, then don't expand it. Fixed bug # 5798.
+
+ * expand.c (recursively_expand_for_file): If we're expanding a
+ variable with no file context, then use the variable's context.
+ Fixes bug # 6195.
+
+2003-10-21 Paul D. Smith <psmith@gnu.org>
+
+ * main.c (log_working_directory): Add newlines to printf()s.
+
+ * README.cvs: Add a note to ignore warnings during autoreconf.
+
+ * maintMakefile (po_repo): Set a new URL for PO file updates.
+ (get-config/config.guess get-config/config.sub): Get these files
+ from the Savannah config project instead of ftp.gnu.org.
+
+2003-10-05 Paul Eggert <eggert@twinsun.com>
+
+ * main.c (main): Avoid potential subscript error if environ has
+ short strings.
+
+2003-08-22 Paul D. Smith <psmith@gnu.org>
+
+ * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
+ systems which don't yet implement the C89 standard :-/.
+
+2003-07-18 Paul D. Smith <psmith@gnu.org>
+
+ * dir.c (directory_contents_hash_1, directory_contents_hash_1)

+ * main.c (print_usage): Remove local declaration of *make_host.
+ (print_version): Display "This program built for ..." after Copyright
+ notice.
+
+2003-05-30 Earnie Boyd <earnie@users.sf.net>
+
+ * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
+ execution of "makeinfo --html make.texi".
+
+2003-04-30 Paul D. Smith <psmith@gnu.org>
+
+ * build.template: Make some changes to maybe allow this script to
+ work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
+
+ * README.OS2.template: New file for OS/2 support. Original
+ contributed by Andreas Buening.
+ * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
+ DOS-style paths.
+
+2003-04-19 Paul D. Smith <psmith@gnu.org>
+
+ Fix bug #1405: allow a target to match multiple pattern-specific
+ variables.
+
+ * rule.c (create_pattern_var, lookup_pattern_var): Move these to
+ variable.c, where they've always belonged.
+ * rule.h: Move the prototypes and struct pattern_var as well.
+ * variable.c (initialize_file_variables): Invoke
+ lookup_pattern_var() in a loop, until no more matches are found.
+ If a match is found, create a new variable set for the target's
+ pattern variables. Then merge the contents of each matching
+ pattern variable set into the target's pattern variable set.
+ (lookup_pattern_var): Change this function to be usable
+ in a loop. It takes a starting position: if NULL, start at the
+ beginning; if non-NULL, start with the pattern variable after that
+ position, and return the next matching pattern.
+ (create_pattern_var): Create a unique instance of
+ pattern-specific variables for every definition in the makefile.
+ Don't combine the same pattern together. This allows us to
+ process the variable handling properly even when the same pattern
+ is used multiple times.
+ (parse_variable_definition): New function: break out the parsing
+ of a variable definition line from try_variable_definition.
+ (try_variable_definition): Call parse_variable_definition to
+ parse.
+ (print_variable_data_base): Print out pattern-specific variables.
+ * variable.h (struct variable): Remember when a variable is
+ conditional. Also remember its flavor.
+ (struct pattern_var): Instead of keeping a variable set, we just
+ keep a single variable for each pattern.
+ * read.c (record_target_var): Each pattern variable contains only a
+ single variable, not a set, so create it properly.
+ * doc/make.texi (Pattern-specific): Document the new behavior.
+
+2003-04-17 Paul D. Smith <psmith@gnu.org>
+
+ * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
+ Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
+ file/directory naming rules for VMS so I can't tell whether this
+ is correct or not.
+
+2003-04-09 Paul D. Smith <psmith@gnu.org>
+
+ * configure.in (HAVE_DOS_PATHS): Define this on systems that need
+ DOS-style pathnames: backslash separators and drive specifiers.
+
+2003-03-28 Paul D. Smith <psmith@gnu.org>
+
+ * file.c (snap_deps): If .SECONDARY with no targets is given, set
+ the intermediate flag on all targets. Fixes bug #2515.

+
+ * job.c: More OS/2 changes from Andreas Buening.
+
+ * file.c (print_file): Fix variable initialization.
+ Fixes bug #2892.
+
+ * remake.c (notice_finished_file):
+
+ * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
+ some calls (like readdir()) return NULL in valid situations
+ without resetting errno. Fixes bug #2846.
+
+2003-02-25 Paul D. Smith <psmith@gnu.org>
+
+ Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
+
+ * job.c (_is_unixy_shell) [OS/2]: New function.
+ Set default shell to /bin/sh.
+ (reap_children): Close the job_rfd pipe here since we don't use a
+ SIGCHLD handler.
+ (set_child_handler_action_flags): define this to empty on OS/2.
+ (start_job_command): Close the jobserver pipe and use
+ child_execute_job() instead of fork/exec.
+ (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
+ rather than exec'ing, then reconfigure stdin/stdout.
+ (exec_command): Rewrite to use spawn instead of exec. Return the
+ PID of the child.
+
+ * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
+ in DOS. Handle the TEMP environment variable as in DOS. Don't
+ use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
+ use -j in DOS mode. Use child_execute_job() instead of
+ exec_command().
+
+ * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
+ spawn() instead.
+
+ * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
+ prototypes that return values.
+
+ * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
+
+ * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
+ * default.c (default_suffixes) [OS/2]: Set proper default suffixes
+ for OS/2.
+ * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
+ DOS paths.
+
+2003-02-24 Paul D. Smith <psmith@gnu.org>
+
+ * default.c [VMS]: New default rules for .cxx -> .obj compiles.
+ * job.c (child_execute_job) [VMS]: New code for handling spawn().
+ (child_execute_job) [VMS]: Handle error status properly.
+ Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
+
+ * function.c (func_shell): Use EINTRLOOP() while reading from the
+ subshell pipe (Fixes bug #2502).
+ * job.c (free_child): Use EINTRLOOP() while writing tokens to the
+ jobserver pipe.
+ * main.c (main): Ditto.
+
+2003-01-30 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (eval): eval() was not fully reentrant, because the
+ collapsed buffer was static. Change it to be an automatic
+ variable so that eval() can be invoked recursively.
+ Fixes bug # 2238.
+ (eval): Apply patch # 1022: fix memory reference error on long
+ target-specific variable lines.
+ Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
+
+ * function.c (check_numeric): Combine the is_numeric() function
+ into this function, since it's only called from one place.
+ Constify this function. Have it print the incorrect string in the
+ error message. Fixes bug #2407.
+ (strip_whitespace): Constify.
+ (func_if): Constify.
+ * expand.c (expand_argument): Constify.
+
+2003-01-29 Paul D. Smith <psmith@gnu.org>
+
+ Fix bug # 2169, also reported by other people on various systems.
+
+ * make.h: Some systems, such as Solaris and PTX, do not fully
+ implement POSIX-compliant SA_RESTART functionality; important
+ system calls like stat() and readdir() can still fail with EINTR
+ even if SA_RESTART has been set on the signal handler. So,
+ introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
+ EINTR for system calls which return -1 or 0 (NULL), respectively,
+ on error.
+ Also, remove the old atomic_stat()/atomic_readdir() and
+ HAVE_BROKEN_RESTART handling.
+
+ * configure.in: Remove setting of HAVE_BROKEN_RESTART.
+
+ * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
+ * remake.c (touch_file): Ditto.
+
+ * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
+ * read.c (construct_include_path): Ditto.

+ (find_directory): Use ENULLLOOP() to wrap opendir().
+ (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
+
+ * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
+ atomic_readdir() handling.
+
+2003-01-22 Paul D. Smith <psmith@gnu.org>
+
+ * function.c (func_call): Fix Bug #1744. If we're inside a
+ recursive invocation of $(call ...), mask any of the outer
+ invocation's arguments that aren't used by this one, so that this
+ invocation doesn't "inherit" them accidentally.
+
+2002-12-05 Paul D. Smith <psmith@gnu.org>
+
+ * function.c (subst_expand): Valery Khamenia reported a
+ pathological performance hit when doing substitutions on very
+ large values with lots of words: turns out we were invoking
+ strlen() a ridiculous number of times. Instead of having each
+ call to sindex() call strlen() again, keep track of how much of
+ the text we've seen and pass the length to sindex().
+
+2002-11-19 Paul D. Smith <psmith@gnu.org>
+
+ * README.cvs, configure.in: Upgrade to require autoconf 2.56.
+
+
+2002-11-16 Paul D. Smith <psmith@gnu.org>
+
+ * NMakefile.template (OBJS): Add hash.c object file.
+ * SMakefile.template (srcs): Ditto.

+ * build_w32.bat: Ditto.
+
+ * Makefile.DOS.template: Remove extra dependencies.
+
+2002-10-25 Paul D. Smith <psmith@gnu.org>
+
+ * expand.c (install_variable_buffer): New function. Install a new
+ variable_buffer context and return the previous one.
+ (restore_variable_buffer): New function. Free the current
+ variable_buffer context and put a previously saved one back.
+ * variable.h: Prototypes for {install,restore}_variable_buffer.
+ * function.c (func_eval): Push a new variable_buffer context
+ before we eval, then restore the old one when we're done.
+ Fixes Bug #1517.
+
+ * read.c (install_conditionals): New function. Install a new
+ conditional context and return the previous one.
+ (restore_conditionals): New function. Free the current
+ conditional context and put a previously saved one back.
+ (eval): Use the {install,restore}_conditionals for "include"
+ handling.
+ (eval_buffer): Use {install,restore}_conditionals to preserve the
+ present conditional state before we evaluate the buffer.
+ Fixes Bug #1516.
+
+ * doc/make.texi (Quick Reference): Add references to $(eval ...)
+ and $(value ...).
+ (Recursion): Add a variable index entry for CURDIR.
+
+ * README.cvs: Update to appropriate versions.
+ * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
+ don't need to copy loadavg.c: automake is smart enough to create
+ it for me. Still have a bug in automake related to ansi2knr tho.
+
+2002-10-14 Paul D. Smith <psmith@gnu.org>
+
+ * remake.c (notice_finished_file): Only touch targets if they have
+ at least one command (as per POSIX). Resolve Bug #1418.
+
+ * *.c: Convert to using ANSI C-style function definitions.
+ * Makefile.am: Enable the ansi2knr feature of automake.
+ * configure.in: ditto.
+
+2002-10-13 Paul D. Smith <psmith@gnu.org>
+
+ * commands.c (set_file_variables): Bug #1379: Don't use alloca()
+ for automatic variable values like $^, etc. In the case of very
+ large lists of prerequisites this causes problems. Instead reuse
+ a static buffer (resizeable) for each variable.
+
+ * read.c (eval): Fix Bug #1391: allow "export" keyword in
+ target-specific variable definitions. Check for it and set an
+ "exported" flag.
+ (record_target_var): Set the export field to v_export if the
+ "exported" flag is set.
+ * doc/make.texi (Target-specific): Document the ability to use
+ "export".
+
+ * doc/make.texi: Change the name of the section on automatic
+ variables from "Automatic" to "Automatic Variables". Added text
+ clarifying the scope of automatic variables.
+
+2002-10-04 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (eval): Allow SysV $$@ variables to use {} braces as well
+ as () braces.
+ (record_files): Ditto.
+
+ * expand.c (variable_expand_string): In $(A:x=y) expansion limit
+ the search for the '=' to only within the enclosing parens.
+
+2002-10-03 Paul D. Smith <psmith@gnu.org>
+
+ Version 3.80 released.
+
+ * dir.c: Change hash functions to use K&R function definition style.
+ * function.c: Ditto.
+ * read.c: Ditto.
+ * variable.c: Ditto.
+
+ Update to automake 1.7.
+
+ * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
+ (pdf): Remove this target as automake now provides one.
+
+ * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
+
+2002-09-30 Martin P.J. Zinser <zinser@decus.de>
+
+ * makefile.com: Updates for GNU make 3.80.
+ * makefile.vms: Ditto.
+
+2002-09-23 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (enum make_word_type): Remove w_comment.
+ (get_next_mword): Don't treat comment characters as special; where
+ this function is used we will never see a comment (it's stripped
+ before we get here) and treating comments specially means that
+ targets like "foo\#bar" aren't handled properly.
+
+2002-09-18 Paul D. Smith <psmith@gnu.org>
+
+ * doc/make.texi (Bugs): Update with some info on Savannah, etc.
+
+ * read.c (eval): Expansion of arguments to export/unexport was
+ ignoring all arguments after the first one. Change the algorithm
+ to expand the whole line once, then parse the results.
+
+2002-09-17 Paul D. Smith <psmith@gnu.org>
+
+ Fix Bug #940 (plus another bug I found while looking at this):
+
+ * read.c (record_target_var): enter_file() will add a new entry if
+ it's a double-colon target: we don't want to do that in this
+ situation. Invoke lookup_file() and only enter_file() if it does
+ not already exist. If the file we get back is a double-colon then
+ add this variable to the "root" double-colon target.
+
+ * variable.c (initialize_file_variables): If this file is a
+ double-colon target but is not the "root" target, then initialize
+ the root and make the root's variable list the parent of our
+ variable list.
+
+2002-09-13 Paul D. Smith <psmith@gnu.org>
+
+ * doc/make.texi (MAKE Variable): Add some indexing for "+".
+
+ * hash.c (round_up_2): Get rid of a warning.
+
+2002-09-12 Paul D. Smith <psmith@gnu.org>
+
+ * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
+ so it doesn't complain about getloadavg.c.
+
+ * commands.c (set_file_variables): Make sure we always alloca() at
+ least 1 character for the value of $? (for '\0').
+
+2002-09-11 Paul D. Smith <psmith@gnu.org>
+
+ * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
+ macro to use RESULT instead of the incorrect _RESULT_.
+
+ * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
+ and atomic_readdir(). We need to #include dirent.h to get this to
+ work.
+ * misc.c (atomic_readdir): Fix typos.
+
+2002-09-10 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (eval): Expand variable lists given to export and
+ unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
+ (conditional_line): Ditto for "ifdef". Fixes bug #103.
+
+ * doc/make.texi (Variables/Recursion): Document this.
+ (Conditional Syntax): And here.
+
+2002-09-09 Paul D. Smith <psmith@gnu.org>
+
+ * configure.in: Check for memmove().
+
+2002-09-07 Paul D. Smith <psmith@gnu.org>
+
+ * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
+ Michael Sterrett <msterret@coat.com> reports that while it has
+ SA_RESTART, it does not work properly.
+
+ * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
+ that invokes stat() and loops to do it again if it returns EINTR.
+ (atomic_readdir): Ditto, with readdir().
+
+ * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
+ and readdir() to atomic_stat() and atomic_readdir().
+
+2002-09-04 Paul D. Smith <psmith@gnu.org>
+
+ * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
+ reports that GNU make sometimes doesn't recognize that targets can
+ be made, when directories can be created as prerequisites. He
+ reports that changing the order of predicates in the DEP->changed
+ flag test so that lookup_file() is always performed, solves this
+ problem.
+
+2002-08-08 Paul D. Smith <psmith@gnu.org>
+
+ * configure.in: Require a newer version of gettext.
+
+ * misc.c (perror_with_name): Translate the format string (for
+ right-to-left language support).
+ (pfatal_with_name): Ditto.
+
+ * main.c: Create a static array of strings to store the usage
+ text. This is done to facilitate translations.
+ (struct command_switch): Remove argdesc and description fields.
+ (switches): Remove values for obsolete fields.
+ (print_usage): Print each element of the usage array.
+
+ * hash.c: Change function definitions to be K&R style.
+
+2002-08-02 Paul D. Smith <psmith@gnu.org>
+
+ * NEWS: Remove the mention of .TARGETS; we aren't going to publish
+ this one because it's too hard to get right. We'll look at it for
+ a future release.
+ * main.c (main): Don't create the .TARGETS variable.
+ * variable.c (handle_special_var): Don't handle .TARGETS.
+
+2002-08-01 Paul D. Smith <psmith@gnu.org>
+
+ * main.c (switches): Add a new option, -B (--always-make). If
+ specified, make will rebuild all targets that it encounters even
+ if they don't appear to be out of date.
+ (always_make_flag): New flag.
+ * make.h: Extern always_make_flag.
+ * remake.c (update_file_1): Check always_make_flag; if it's set we
+ will always rebuild any target we can, even if none of its
+ prerequisites are newer.
+ * NEWS: Mention it.
+
+ * doc/make.texi (Shell Function): Make it clear that make
+ variables marked as "export" are not passed to instances of the
+ shell function.
+
+ Add new introspection variable .VARIABLES and .TARGETS.
+
+ * variable.c (handle_special_var): New function. If the variable
+ reference passed in is "special" (.VARIABLES or .TARGETS),
+ calculate the new value if necessary. .VARIABLES is handled here:
+ walk through the hash of defined variables and construct a value
+ which is a list of the names. .TARGETS is handled by
+ build_target_list().
+ (lookup_variable): Invoke handle_special_var().
+ * file.c (build_target_list): Walk through the hask of known files
+ and construct a list of the names of all the ones marked as
+ targets.
+ * main.c (main): Initialize them to empty (and as simple variables).
+ * doc/make.texi (Special Variables): Document them.
+ * NEWS: Mention them.
+
+ * variable.h (struct variable): Add a new flag "exportable" which
+ is true if the variable name is valid for export.
+ * variable.c (define_variable_in_set): Set "exportable" when a new
+ variable is defined.
+ (target_environment): Use the "exportable" flag instead of
+ re-checking the name here... an efficiency improvement.
+
+2002-07-31 Paul D. Smith <psmith@gnu.org>
+
+ * config.h-vms.template: Updates to build on VMS. Thanks to
+ Brian_Benning@aksteel.com for helping verify the build.
+ * makefile.com: Build the new hash.c file.
+ * hash.h: Use strcpmi(), not stricmp(), in the
+ HAVE_CASE_INSENSITIVE_FS case.
+
+2002-07-30 Paul D. Smith <psmith@gnu.org>
+
+ * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
+ backslashes to the HAVE_CASE_INSENSITIVE_FS case.
+ Reported by <Brian_Benning@aksteel.com>.
+
+2002-07-10 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (pop_variable_scope): Remove variable made unused by
+ new hash infrastructure.
+ * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime

+
+
+ Installed Greg McGary's integration of the hash functions from the
+ GNU id-utils package:
+
+2002-07-10 Greg McGary <greg@mcgary.org>
+
+ * scripts/functions/filter-out: Add literals to to the
+ pattern space in order to add complexity, and trigger
+ use of an internal hash table. Fix documentation strings.
+ * scripts/targets/INTERMEDIATE: Reverse order of files
+ passed to expected `rm' command.
+
+2002-07-10 Greg McGary <greg@mcgary.org>

+
+2002-07-10 Paul D. Smith <psmith@gnu.org>
+
+ Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
+ prerequisite list. A real SysV make will expand the entire
+ prerequisites list _twice_: we don't do that as it's a big
+ backward-compatibility problem. We only replace those specific
+ variables.
+
+ * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
+ references left in the list of prerequisites. Check for .POSIX as
+ we record targets, so we can disable non-POSIX behavior while
+ reading makefiles as well as running them.
+ (eval): Check the prerequisite list to see if we have anything
+ that looks like a SysV prerequisite variable reference.
+
+2002-07-09 Paul D. Smith <psmith@gnu.org>
+
+ * doc/make.texi (Prerequisite Types): Add a new section describing
+ order-only prerequisites.
+
+ * read.c (uniquize_deps): If we have the same file as both a
+ normal and order-only prereq, get rid of the order-only prereq,
+ since the normal one supersedes it.
+
+2002-07-08 Paul D. Smith <psmith@gnu.org>
+
+ * AUTHORS: Added Greg McGary to the AUTHORS file.
+ * NEWS: Blurbed order-only prerequisites.
+ * file.c (print_file): Show order-only deps properly when printing
+ the database.
+
+ * maintMakefile: Add "update" targets for wget'ing the latest
+ versions of various external files. Taken from Makefile.maint in
+ autoconf, etc.
+
+ * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
+ Reported by Eli Zaretskii <eliz@is.elta.co.il>.
+
+2002-07-07 Paul D. Smith <psmith@gnu.org>
+
+ * po/*.po: Remove. We'll use wget to retrieve them at release
+ time.
+
+ * variable.c (do_variable_definition) [W32]: On W32 using cmd
+ rather than a shell you get an exception. Make sure we look up
+ the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
+
+ * remake.c (notice_finished_file): Fix handling of -t flag.
+ Patch provided by Henning Makholm <henning@makholm.net>.
+
+ * implicit.c (pattern_search): Some systems apparently run short
+ of stack space, and using alloca() in this function caused an
+ overrun. I modified it to use xmalloc() on the two variables
+ which seemed like they might get large. Fixes Bug #476.
+
+ * main.c (print_version): Update copyright notice to conform with
+ GNU standards.
+ (print_usage): Update help output.
+
+ * function.c (func_eval): Create a new make function, $(eval
+ ...). Expand the arguments, put them into a buffer, then invoke
+ eval_buffer() on the resulting string.
+ (func_quote): Create a new function, $(quote VARNAME). Inserts
+ the value of the variable VARNAME without expanding it any
+ further.
+
+ * read.c (struct ebuffer): Change the linebuffer structure to an
+ "eval buffer", which can be either a file or a buffer.
+ (eval_makefile): Move the code in the old read_makefile() which
+ located a makefile into here: create a struct ebuffer with that
+ information. Have it invoke the new function eval() with that
+ ebuffer.
+ (eval_buffer): Create a new function that creates a struct ebuffer
+ that holds a string buffer instead of a file. Have it invoke
+ eval() with that ebuffer.
+ (eval): New function that contains the guts of the old
+ read_makefile() function: this function parses makefiles. Obtains
+ data to parse from the provided ebuffer. Some modifications to
+ make the flow of the function cleaner and clearer. Still could
+ use some work here...
+ (do_define): Takes a struct ebuffer instead of a FILE*. Read the
+ contents of the define/endef variable from the ebuffer.
+ (readstring): Read the next line from a string-style ebuffer.
+ (readline): Read the next line from an ebuffer. If it's a string
+ ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
+ from the file.
+
+ * dep.h (eval_buffer): Prototype eval_buffer();
+
+ * variable.c (do_variable_definition): Make sure that all
+ non-target-specific variables are registered in the global set.
+ If we're invoked from an $(eval ...) we might be inside a $(call
+ ...) or other function which has pushed a variable scope; we still
+ want to define our variables from evaluated makefile code in the
+ global scope.
+
+2002-07-03 Greg McGary <greg@mcgary.org>
+
+ * dep.h (struct dep) [ignore_mtime]: New member.
+ [changed]: convert to a bitfield.

+ * main.c (main, handle_non_switch_argument): Likewise.
+ * rule.c (convert_suffix_rule): Likewise.
+ * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
+ (read_makefile): Parse '|' in prerequisite list.
+ (uniquize_deps): Consider ignore_mtime when comparing deps.
+ * remake.c (update_file_1, check_dep): Don't force remake for
+ dependencies that have d->ignore_mtime.
+ * commands.c (FILE_LIST_SEPARATOR): New constant.
+ (set_file_variables): Don't include a
+ prerequisite in $+, $^ or $? if d->ignore_mtime.
+ Define $|.
+
+2002-06-18 Paul D. Smith <psmith@gnu.org>
+
+ * make.texinfo: Updates for next revision. New date/rev/etc.
+ Recreate all Info menus. Change license on the manual to the GNU
+ Free Documentation License. A number of typos.
+ (Variables Simplify): Don't use "-" before it's defined.
+ (Automatic Prerequisites): Rewrite the target example to work
+ properly if the compile fails. Remove incorrect comments about
+ how "set -e" behaves.
+ (Text Functions): Move the "word", "wordlist", "words", and
+ "firstword" functions here, from "File Name Functions".
+ * make-stds.texi: Update from latest GNU version.
+ * fdl.texi: (created) Import the latest GNU version.
+
+2002-06-06 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (do_variable_definition): New function: extract the
+ part of try_variable_definition() that actually sets the value
+ into a separate function.
+ (try_variable_definition): Call do_variable_definition() after
+ parsing the variable definition string.
+ (define_variable_in_set): Make the name argument const.
+
+ * variable.h (enum variable_flavor): Make public.
+ (do_variable_definition): Create prototype.
+
+ * read.c (read_all_makefiles): Create a new built-in variable,
+ MAKEFILE_LIST.
+ (read_makefile): Add each makefile read in to this variable value.
+
+2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
+
+ * Makefile.DOS.template: Tweak according to changes in the
+ distribution. Add back the dependencies of *.o files.
+
+ * configh.dos.template: Synchronize with config.h.in.
+
+2002-05-09 Paul D. Smith <psmith@gnu.org>
+
+ * file.c (file_timestamp_now): Use K&R function declaration.
+
+ * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
+ getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
+ #undef it. Remove predefined setup of NLIST_STRUCT. Decide
+ whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
+ NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
+ * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
+ nlist.n_name is a pointer rather than an array.
+
+ * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
+ version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
+ * configure.in: Use it instead of the old version.
+
+ * main.c (main): Prefer setvbuf() to setlinebuf().
+
+2002-05-08 Paul D. Smith <psmith@gnu.org>
+
+ * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
+ (loadavg_LDADD): Ditto.
+
+2002-04-29 Paul D. Smith <psmith@gnu.org>
+
+ * expand.c (recursively_expand_for_file): Rename
+ recursively_expand() to recursively_expand_for_file() and provide
+ an extra argument, struct file. If the argument is provided, set
+ the variable scope to that of the file before expanding.
+ * variable.h (recursively_expand): Make this a macro that invokes
+ recursively_expand_for_file() with a NULL file pointer.
+ * variable.c (target_environment): Call the renamed function and
+ provide the current file context.
+ Fixes Debian bug #144306.
+
+2002-04-28 Paul D. Smith <psmith@gnu.org>
+
+ Allow $(call ...) user-defined variables to be self-referencing
+ without throwing an error. Allows implementation of transitive
+ closures, among other possibly useful things.
+ Requested by: Philip Guenther <guenther@sendmail.com>
+
+ * variable.h (struct variable): Add a new field: exp_count, and
+ new macros to hold its size and maximum value.
+ (warn_undefined): Make this a macro.
+ * variable.c (define_variable_in_set): Initialize it.
+ * expand.c (recursively_expand): If we detect recursive expansion
+ of a variable, check the exp_count field. If it's greater than 0
+ allow the recursion and decrement the count.
+ (warn_undefined): Remove this (now a macro in variable.h).
+ * function.c (func_call): Before we expand the user-defined
+ function, modify its exp_count field to contain the maximum
+ number of recursive calls we'll allow. After the call, reset it
+ to 0.
+
+2002-04-21 Paul D. Smith <psmith@gnu.org>
+
+ Modified to use latest autoconf (2.53), automake (1.6.1), and
+ gettext (0.11.1). We're using gettext's new "external" support,
+ to avoid including libintl source with GNU make.
+
+ * README.cvs: New file. Explain how to build GNU make from CVS.
+
+ * configure.in: Modify checking for the system glob library.
+ Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
+ GLOBDIR (we will always put "glob" in SUBDIRS, so automake
+ etc. will manage it correctly). Set an automake conditional
+ USE_LOCAL_GLOB to decide whether to compile the glob library.
+
+ * getloadavg.c (main): Include make.h in the "TEST" program to
+ avoid warnings.
+
+ * Makefile.am: Remove special rules for loadavg. Replace them
+ with Automake capabilities for building extra programs.
+
+ * signame.c: This file does nothing if the system provide
+ strsignal(). If not, it implements strsignal(). If the system
+ doesn't define sys_siglist, then we make our own; otherwise we use
+ the system version.
+ * signame.h: Removed.
+
+ * main.c (main): No need to invoke signame_init(). Update copyright.
+
+ * ABOUT-NLS: Removed.
+ * gettext.c: Removed.
+ * gettext.h: Get a simplified copy from the gettext package.
+ * po/*: Created.
+ * i18n/*.po: Moved to po/.
+ * i18n/: Removed.
+
+ * config/*: Created. Contains package configuration helper files.
+ * config.guess, config.sub: Moved to config directory.
+
+ * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
+ Rework to use new-style autoconf features. Use the "external"
+ mode for gettext. Make the build.sh config file conditional on
+ whether build.sh.in exists, to avoid autoconf errors.
+ * acinclude.m4: Removed almost all macros as being obsolete.
+ Rewrote remaining macros to use AC_DEFINE.
+ * acconfig.h: Removed.
+
+ * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
+ conditional to handle customs support. Remove special handling
+ for i18n features.
+
+2002-04-20 Paul D. Smith <psmith@gnu.org>
+
+ * function.c (func_call): Don't mark the argument variables $1,
+ etc. as recursive. They've already been fully expanded so
+ there's no need to do it again, and doing so strips escaped $'s.
+ Reported by Sebastian Glita <glseba@yahoo.com>.
+
+ * remake.c (notice_finished_file): Walk through double-colon
+ entries via the prev field, not the next field!
+ Reported by Greg McGary <greg@mcgary.org>.
+
+ * main.c (main): If the user specifies -q and asks for a specific
+ target which is a makefile, we got an assert. In that case it
+ turns out we should continue normally instead.
+
+ * i18n/de.po, i18n/fr.po: Installed an updated translation.
+
+ * i18n/he.po: Installed a new translation.
+
+2002-01-07 Paul D. Smith <psmith@gnu.org>
+
+ * i18n/es.po, i18n/ru.po: Installed an updated translation.
+
+2001-12-04 Paul D. Smith <psmith@gnu.org>
+
+ * i18n/ja.po: Installed an updated translation.
+
+2001-09-06 Paul Eggert <eggert@twinsun.com>
+
+ * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
+ (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
+
+ * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
+ are available.
+ (main): Get rid of any avoidable limit on stack size.
+
+2001-09-04 Paul D. Smith <psmith@gnu.org>
+
+ * i18n/da.po: Installed an updated translation.
+
+2001-08-03 Paul D. Smith <psmith@gnu.org>
+
+ * i18n/fr.po: Installed an updated translation.
+ Resolves Debian bug #106720.
+
+2001-06-13 Paul D. Smith <psmith@gnu.org>
+
+ * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
+ translation.
+
+2001-06-11 Paul D. Smith <psmith@gnu.org>
+
+ * i18n/ko.po: Installed a new translation.
+
+2001-05-06 Paul D. Smith <psmith@gnu.org>
+
+ Modify the EINTR handling.
+
+ * job.c (new_job): Reorganize the jobserver algorithm. Reorder
+ the way in which we manage the file descriptor/signal handler race
+ trap to be more efficient.
+
+2001-05-06 Paul Eggert <eggert@twinsun.com>
+
+ Restart almost all system calls that are interrupted, instead
+ of worrying about EINTR. The lone exception is the read() for
+ job tokens.
+
+ * configure.in (HAVE_SA_RESTART): New macro.
+ (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
+ * main.c (main): Use SA_RESTART instead of the old,
+ nonstandard SA_INTERRUPT.
+
+ * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
+ * main.c (bsd_signal): New function or macro,
+ if the implementation doesn't supply it.
+ (The bsd_signal function will be in POSIX 1003.1-200x.)
+ (HANDLESIG): Remove.
+ (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
+
+ * make.h (EINTR_SET): Remove.
+ (SA_RESTART): New macro.
+
+ * arscan.c (ar_member_touch): Don't worry about EINTR.
+ * function.c (func_shell): Likewise.
+ * job.c (reap_children, free_child, new_job): Likewise.
+ * main.c (main): Likewise.
+ * remake.c (touch_file, name_mtime): Likewise.
+
+ * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
+ if fstat failed with errno!=EINTR, the error was ignored.
+
+ * job.c (set_child_handler_action_flags): New function.
+ (new_job): Use it to temporarily clear the SIGCHLD action flags
+ while reading the token.
+
+2001-05-02 Paul D. Smith <psmith@gnu.org>
+
+ * job.c (start_job_command): Don't add define/endef per-line flags
+ to the top-level flags setting.
+
+2001-04-03 Paul D. Smith <psmith@gnu.org>
+
+ * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
+ bit on error, so check for odd return values, not non-0 return
+ values.
+ (VMS_get_member_info): Calculate the timezone differences correctly.
+ Reported by John Fowler <jfowler@nyx.net>.
+
+
+2001-03-14 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (lookup_variable) [VMS]: Null-terminate the variable
+ value before invoking define_variable().
+ Reported by John Fowler <jfowler@nyx.net>.
+
+2001-02-07 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (record_target_var): If we reset the variable due to a
+ command-line variable setting overriding it, turn off the "append"
+ flag.
+
+2001-01-17 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (lookup_variable) [VMS]: When getting values from the
+ environment, allocate enough space for the _value_ plus escapes,
+ not enough space for the name plus escapes :-/.
+ Reported by John Fowler <jfowler@nyx.net>.
+
+ * remake.c (f_mtime): Removed the "***" prefix from the mod time
+ warnings that make generates, so it doesn't look like an error.
+ Reported by Karl Berry <karl@gnu.org>.
+
+
+ Fix for PR/2020: Rework appended target-specific variables. I'm
+ fairly confident this algorithm is finally correct.
+
+ * expand.c (allocated_variable_append): Rewrite. Instead of
+ expanding each appended variable then adding all the expanded
+ strings together, we append all the unexpanded values going up
+ through the variable set contexts, then expand the final result.
+ This behaves just like non-target-specific appended variable
+ values, while the old way didn't in various corner cases.
+ (variable_append): New function: recursively append the unexpanded
+ value of a variable, walking from the outermost variable scope to
+ the innermost.
+ * variable.c (lookup_variable): Remove the code that looked up the
+ variable set list if the found variable was "append". We don't
+ need this anymore.
+ (lookup_variable_in_set): Make this non-static so we can use it
+ elsewhere.
+ (try_variable_definition): Use lookup_variable_in_set() rather
+ than faking out current_variable_set_list by hand (cleanup).
+ * variable.h: Add a prototype for the now non-static
+ lookup_variable_in_set().
+
+2000-11-17 Paul D. Smith <psmith@gnu.org>
+
+ * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
+ WINDOWS32 port to assume timestamps can be up to 3 seconds away
+ before throwing a fit.
+
+2000-11-17 Paul D. Smith <psmith@gnu.org>
+
+ * read.c (readline): CRLF calculations had a hole, if you hit the
+ buffer grow scenario just right. Reworked the algorithm to avoid
+ the need for len or lastlen at all. Problem description with
+ sample code chages provided by Chris Faylor <cgf@redhat.com>.
+
+2000-10-24 Paul D. Smith <psmith@gnu.org>
+
+ * gettext.c (SWAP): Declare this with the prototype, otherwise
+ some systems don't work (non-32-bit? Reported for Cray T3E).
+ Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
+
+2000-10-05 Paul D. Smith <psmith@gnu.org>
+
+ * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
+ AM_LC_MESSAGES; it doesn't seem to do anything anyway??
+
+ * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
+
+2000-09-22 Paul D. Smith <psmith@gnu.org>
+
+ * gettext.c: Don't #define _GETTEXT_H here; we only include some
+ parts of the real gettext.h here, and we expect to really include
+ the real gettext.h later. If we keep this #define, it's ignored.
+
+2000-09-21 Paul D. Smith <psmith@gnu.org>
+
+ * main.c (log_working_directory): Rework the text to use complete
+ sentences, to make life simpler for the translators.
+
+2000-08-29 Paul D. Smith <psmith@gnu.org>
+
+ * file.c (remove_intermediates): Print a debug message before we
+ remove intermediate files, so the user (if she uses -d) knows
+ what's going on.
+
+2000-08-21 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (try_variable_definition): Change how we handle
+ target-specific append variable defns: instead of just setting the
+ value, expand it as an append _but_ only within the current
+ target's context. Otherwise we lose all but the last value if the
+ variable is appended more than once within the current target
+ context. Fixes PR/1831.
+
+2000-08-16 Paul D. Smith <psmith@gnu.org>
+
+ * function.c (func_shell): Nul-terminate the buffer before
+ printing an exec error message (just in case it's not!).
+ Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
+
+2000-07-25 Paul D. Smith <psmith@gnu.org>
+
+ * job.c (construct_command_argv_internal): Add "~" to the list of
+ sh_chars[] which disallow optimizing out the shell call.
+
+2000-07-23 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
+ supersedes --disable-nsec-timestamps.
+ * make.texinfo: Consistently use "time stamp" instead of "timestamp".
+ * README: Remove --disable-nsec-timestamps.
+
+ * filedef.h (struct file.low_resolution_time): New member.
+ * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
+ * remake.c (update_file_1):
+ Avoid spurious rebuilds due to low resolution time stamps,
+ generalizing the earlier code that applied only to archive members.
+ (f_mtime): Archive members always have low resolution time stamps.
+
+ * configure.in: Remove --disable-nsec-timestamps, as this has
+ been superseded by .LOW_RESOLUTION_TIME.
+
+2000-07-23 Paul Eggert <eggert@twinsun.com>
+
+ * configure.in (enable_nsec_timestamps): Renamed from
+ make_cv_nsec_timestamps, since enable/disable options
+ shouldn't be cached.
+
+2000-07-23 Bruno Haible <haible@clisp.cons.org>
+ and Paul Eggert <eggert@twinsun.com>
+
+ * file.c (file_timestamp_now):
+ Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
+ so that clock_gettime is not linked unless needed.
+
+ * filedef.h (FILE_TIMESTAMP_HI_RES):
+ Remove definition; "configure" now does this.
+
+ * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
+ to before high resolution file timestamp check,
+ since that check now uses uintmax_t.
+ (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
+ high resolution file timestamps.
+ (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
+ so that we don't link in clock_gettime unnecessarily.
+
+2000-07-17 Paul D. Smith <psmith@gnu.org>
+
+ * i18n/ja.po: New version of the translation file.
+
+2000-07-07 Paul D. Smith <psmith@gnu.org>
+
+ * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
+ the offset calculation.
+ (name_mtime): Replace EINTR test with EINTR_SET macro.
+
+2000-07-07 Paul Eggert <eggert@twinsun.com>
+
+ Fix for PR/1811:
+
+ * remake.c (update_file_1):
+ Avoid spurious rebuilds of archive members due to their
+ timestamp resolution being only one second.
+ (f_mtime): Avoid spurious warnings of timestamps in the future due to
+ the clock's resolution being lower than file timestamps'.
+ When warning about future timestamps, report only the discrepancy,
+ not the absolute value of the timestamp and the current time.
+
+ * file.c (file_timestamp_now): New arg RESOLUTION.
+ * filedef.h (file_timestamp_now): Likewise.
+ (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
+
+2000-07-05 Paul D. Smith <psmith@gnu.org>
+
+ * variable.c (lookup_variable) [VMS]: Remove vestigial references
+ to listp. Fixes PR/1793.
+
+2000-06-26 Paul Eggert <eggert@twinsun.com>
+
+ * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
+
+ * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
+
+ * remake.c (f_mtime): Remove unused var memtime.
+
+2000-06-25 Martin Buchholz <martin@xemacs.org>
+
+ * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
+ Ran spell-check on make.texinfo.
+
+2000-06-23 Paul D. Smith <psmith@gnu.org>
+
+ * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
+ EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
+ * make.h: Define these macros.
+
+ * Version 3.79.1 released.
+
+ * configure.in: Add a new option, --disable-nsec-timestamps, to
+ avoid using sub-second timestamps on systems that support it. It
+ can lead to problems, e.g. if your makefile relies on "cp -p".
+ * README.template: Document the issue with "cp -p".
+
+ * config.guess, config.sub: Updated.
