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. + * implicit.c (pattern_search): Zero ignore_mtime. + * 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.

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.
