	--with-systemdsystemunitdir=\$${prefix}/lib/systemd/system.

2019-01-05  Colin Watson  <cjwatson@debian.org>

2019-01-05  Colin Watson  <cjwatson@debian.org>

	sandbox: Work around Microsoft SCEP

	This is a proprietary antivirus program and I've only been able to guess
	at how to handle it.  Note that it is no longer supported by Microsoft
	and so users should probably replace it with something else, but I still
	want to minimise the number of support requests I get related to it.

	* lib/sandbox.c (make_seccomp_filter): If libscep_pac.so is preloaded,
	then allow some system calls related to sockets and System V message
	queues.
	* NEWS: Document this.

2018-12-24  Colin Watson  <cjwatson@debian.org>

	Use (void *) 0 as a variadic sentinel

	NULL is formally incorrect here since the standard allows it to be an
	integer constant expression.

	* lib/decompress.c (decompress_open, decompress_fdopen): Use (void *)
	rather than NULL as a sentinel for variadic functions.
	* libdb/db_delete.c (dbdelete): Likewise.

	setenv_less, add_output_iconv, make_display_command, tmp_cat_filename,
	format_display_and_save, format_display, display_catman, display,
	local_man_loop): Likewise.
	* src/manconv_client.c (add_manconv): Likewise.
	* src/manconv_main.c (parse_opt): Likewise.
	* src/manp.c (pathappend, add_nls_manpaths, add_system_manpath,
	add_dir_to_path_list, get_catpath): Likewise.

2018-12-06  Colin Watson  <cjwatson@debian.org>

	@cache_top_owner@.
	* init/systemd/man-db.service.in (ExecStart, User): Use

2018-12-06  Colin Watson  <cjwatson@debian.org>

	Improve systemd unit commentary

	* init/systemd/man-db.service.in (ExecStart): Add comment.

2018-12-06  Colin Watson  <cjwatson@debian.org>

	Allow disabling installation of systemd components

	Automake conditional (true unless --with-systemdsystemunitdir=no).
	* init/systemd/Makefile.am: Honour INSTALL_SYSTEMD_TMPFILES and
	INSTALL_SYSTEMD_TIMER.

2018-12-06  Colin Watson  <cjwatson@debian.org>

	* .gitignore: Add init/systemd/man-db.service.
	* NEWS: Document this.

2018-11-14  Colin Watson  <cjwatson@debian.org>

	Fix incorrect error message

	Reported by Julian Gilbey.  Fixes Debian bug #913721.

	* src/man.c (check_standard_fds): Correct error message if stdout is not
	open for writing (not "for reading", as previously claimed).

2018-11-09  Colin Watson  <cjwatson@debian.org>

	release.sh: Simplify Lex handling

	release.sh had a hack to ensure that flex-generated scanners are fresh
	in release tarballs.  This is more easily achieved by configuring with
	--enable-maintainer-mode, which causes Automake to enable the Lex
	rebuild rule.

	* release.sh: Configure with --enable-maintainer-mode; drop conditional
	removals of src/lexgrog.c and src/zsoelim.c.

2018-11-09  Colin Watson  <cjwatson@debian.org>

	lexgrog: Fix handling of \- in RHS of NAME section

	Fixes Debian bug #913351.

	* src/lexgrog.l (MAN_NAME): Split into MAN_NAME (left-hand side) and
	MAN_DESC (right-hand side).  Most rules remain as before, except that \-
	and similar are only handled specially in MAN_NAME and transition to
	MAN_DESC, and rules that add a 0x11 marker (indicating the start of a
	new whatis definition) transition to MAN_NAME.
	(MAN_NAME_AT, MAN_NAME_BSX, MAN_NAME_BX, MAN_NAME_BX_RELEASE,
	MAN_NAME_DQ, MAN_NAME_FX, MAN_NAME_NX, MAN_NAME_OX): Rename to
	MAN_DESC_*.
	(mdoc_text): Transition to MAN_DESC rather than MAN_NAME.
	(newline_found): If adding 0x11, transition to MAN_NAME.
	* src/tests/lexgrog-3: New file.
	* src/tests/Makefile.am (ALL_TESTS): Add lexgrog-3.
	* NEWS: Document this.

2018-11-09  Colin Watson  <cjwatson@debian.org>

	* NEWS: Document changes since 2.8.4.

2018-11-09  Colin Watson  <cjwatson@debian.org>

	lexgrog: Add test for multiple whatis definitions

	* src/tests/lexgrog-2: New file.
	* src/tests/Makefile.am (ALL_TESTS): Add lexgrog-2.

2018-11-09  Colin Watson  <cjwatson@debian.org>

	lexgrog: Tidy up rules section

	No functional change.

	* src/lexgrog.l: Make more use of start condition scopes.  Reindent
	rules somewhat to make better use of vertical space.

2018-11-03  Nikola Forró  <nforro@redhat.com>

	Fix several resource and memory leaks

	* lib/decompress.c (decompress_zlib): Fix fd leak if gzdopen fails.
	* lib/encodings.c (find_charset_locale): Free locale if setlocale fails.
	* src/man.c (make_roff_command): Free fmt_prog.
	* src/mandb.c (process_manpath): Free catpath if manpath is not a
	directory.
	* src/whatis.c (do_apropos): Free found_here.

	better diffs in future.

2018-10-21  Chen Qi  <Qi.Chen@windriver.com>

	man-arg-config-file: fix to use config_file

	* m4/man-arg-config-file.m4: Compute config_file_basename based on
	config_file, not withval.

2018-08-20  Colin Watson  <cjwatson@debian.org>

	Fail to configure if flex is needed but missing

	Fixes Savannah bug #54541.

	* configure.ac: Issue an error if AC_PROG_LEX didn't find a lexer
	generator and either src/lexgrog.c or src/zsoelim.c is missing (as may
	be the case when building from a git clone rather than a released
	tarball).

2018-08-02  Colin Watson  <cjwatson@debian.org>

	Fix warning from gcc -Wcast-function-type

	This exposed the fact that errors from unlink in the cleanup path were
	previously ignored.  We now issue a warning in the same way that
	commit_tmp_cat does.

	* src/man.c (cleanup_unlink): New function.
	(open_cat_stream, close_cat_stream, display_catman): Use cleanup_unlink
	rather than an incorrect cast of unlink.

2018-07-27  Colin Watson  <cjwatson@debian.org>

	* Version: 2.8.4.

2018-07-27  Colin Watson  <cjwatson@debian.org>

	Work around Gnulib/gettext mismatch

	The versions of gettext infrastructure files installed by gnulib-tool
	don't necessarily match our configured AM_GNU_GETTEXT_VERSION, so we
	need to fix things up in bootstrap.

	* bootstrap.conf (gnulib_tool_option_extras): Set --po-base to gl/ref-po
	rather than gnulib/po.
	(bootstrap_post_import_hook): Merge temporary gl/ref-po directory into
	gl/po.

2018-07-27  Colin Watson  <cjwatson@debian.org>

	Upgrade to Gnulib 20180726

	* bootstrap.conf (GNULIB_REVISION): Set to
	900ca5c0b092e50f9f17329feea3fbfe2b6e2139.

	sandbox: Improve ESET compatibility further

	* lib/sandbox.c (make_seccomp_filter): If libesets_pac.so is preloaded,
	then allow msgset (second argument 0) and msgsnd.
	* NEWS: Document this.

2018-07-15  Colin Watson  <cjwatson@debian.org>

	sandbox: Allow some shared memory operations

	These were previously only allowed when ESET File Security is in use,
	but the Astrill VPN seems to require something similar, there are
	doubtless other such preload hacks, and they're relatively harmless.

	* lib/sandbox.c (make_seccomp_filter): Allow shmat (third argument
	SHM_RDONLY), shmctl (second argument IPC_STAT), shmdt, and shmget
	regardless of preloads.
	* NEWS: Document this.

2018-06-08  Colin Watson  <cjwatson@debian.org>

	Check for external formatter in correct directory

	Check for mandb_nfmt and mandb_tfmt in the manual page hierarchy as
	documented, not in the current directory.  This was broken by the
	working-directory-handling changes in 2.8.3.

	Reported by Josh Triplett.  Fixes Debian bug #901007.

	* src/man.c (NFMT_PROG, TFMT_PROG): Remove leading "./".
	(make_roff_command): Refactor confusing #ifdef forest.  Prefix dir to
	TFMT_PROG/NFMT_PROG rather than looking in the current directory.  Don't
	look for an external formatter at all if dir is NULL.
	* NEWS: Document this.

2018-06-08  Colin Watson  <cjwatson@debian.org>

	Define an access(2) wrapper with clearer semantics

	As usual for system calls, access(2) returns zero on success.  However,
	I generally think of it as "can we access this file in this way", where
	boolean semantics would be more convenient, and find it too easy to
	invert logic by accident when using the system call directly.  Define a
	CAN_ACCESS wrapper with boolean semantics.

	* include/manconfig.h.in (CAN_ACCESS): New macro.
	* lib/tempfile.c (path_search): Use CAN_ACCESS.
	* src/catman.c (check_access): Likewise.
	* src/filenames.c (make_filename): Likewise.
	* src/man.c (make_roff_command, display): Likewise.
	* src/ult_src.c (find_include): Likewise.
	* src/whatis.c (use_grep): Likewise.

	* man/THANKS: Update translator credit.

2018-05-29  Colin Watson  <cjwatson@debian.org>

	Add po4a-based Spanish manual page translation

	This supersedes the previous whole-file translations, which had not been
	properly updated in many years.

	* man/po4a/po/es.po: New from Translation Project (thanks, Francisco
	Javier Serrador).
	* man/LINGUAS: Remove es.
	* man/LINGUAS.po4a: Add es.
	* man/es/Makefile.am (PO4A_LINGUA): Set to yes.

	man/es/man8/catman.man8, man/es/man8/mandb.man8: Remove.
	* man/es/translator.add: New file.
	* man/po4a/Makefile.am (POFILES): Add po/es.po.
	* man/po4a/po4a.cfg (po4a_langs): Add es.
	* man/THANKS: Update translator credit.
	* .gitignore: Add man/es/man1, man/es/man5, and man/es/man8.

2018-05-29  Colin Watson  <cjwatson@debian.org>

	equivalent to free.
	* lib/hashtable.h (plain_hashtable_free): Remove.
	* lib/orderfiles.c (order_files): Use free rather than
	plain_hashtable_free.
	* libdb/db_btree.c (btree_findkey): Likewise.

	* lib/pathsearch.c (pathsearch, directory_on_path): Remove useless
	if-before-free.

	invoked with an absolute path.

	* bootstrap.conf (gnulib_modules): Add progname.
	* include/manconfig.h.in (program_name): Remove.
	* src/accessdb.c (main): Call set_program_name rather than similar
	hand-rolled code.
	* src/catman.c (main): Likewise.  Don't free program_name.
	* src/globbing_test.c (main): Likewise.
	* src/lexgrog_test.c (main): Likewise.

	* src/manpath.c (main): Likewise.
	* src/tests/fspause.c (main): Likewise.
	* src/whatis.c (main): Likewise.
	* src/zsoelim_main.c (main): Likewise.

	* src/man.c (manopt_to_env): Run program_name through base_name, since
	that's no longer necessarily done up-front.
	* src/whatis.c (main): Run program_name through base_name before
	comparing it to APROPOS_NAME, since that's no longer necessarily done
	up-front.

2018-05-29  Colin Watson  <cjwatson@debian.org>

	Upgrade to Gnulib 20180527

	* bootstrap.conf (GNULIB_URL): Remove.

	(gnulib_modules): Replace gettext with gettext-h.
	(gnulib_tool_option_extras): Remove --no-cache-modules (accidental
	leftover from earlier testing).
	(local_gl_dir): Set to 'gnulib-local' to avoid confusion with 'gl' as
	the local output directory.  Remove 'rm -rf gl' hack, now superseded.
	(buildreq): Bump minimum autopoint and gettext versions to 0.18.3,
	matching previous change to configure.ac.
	* configure.ac (AM_PROG_AR, LT_INIT): Move below gl_EARLY.
	* patches/argp-domain.patch: Rebase.
	* src/tests/Makefile.am (TESTS_ENVIRONMENT): Remove use of

	docs/INSTALL.autoconf, po/Makefile.in.in, po/Makevars, po/Rules-quot,

	* bootstrap, bootstrap.conf: New files.
	* Makefile.am (GNULIB_PO, SUBDIRS, EXTRA_DIST, ACLOCAL_AMFLAGS): Refer

	Suppress spurious gettext headers in --help output

	Some of man-db's commands have post-options help text but no pre-options
	help text.  Unfortunately, the way this works in argp (separating the
	two sections using a '\v' character) means that this results in argp
	trying to translate the empty string, which produces gettext catalog
	headers.  The easiest way to suppress this odd behaviour seems to be to
	use a help filter function, so do that.

	Reported by Rafael Fontenelle.

	* src/accessdb.c (help_filter): Return NULL for ARGP_KEY_HELP_PRE_DOC.
	* src/lexgrog_text.c (help_filter): New function.

	sandbox: Generalise libesets_pac.so check slightly

	* lib/sandbox.c (make_seccomp_filter): LD_PRELOAD or /etc/ld.so.preload

	search slightly more permissive.

2018-02-20  Colin Watson  <cjwatson@debian.org>

	sandbox: Handle /etc/ld.so.preload

	At least ESET File Security may be configured using /etc/ld.so.preload
	rather than the LD_PRELOAD environment variable, so unfortunately we
	need to check that too.

	* lib/sandbox.c (search_ld_preload): New function, handling both
	LD_PRELOAD and /etc/ld.so.preload.
	(can_load_seccomp, make_seccomp_filter): Use search_ld_preload.

2018-02-19  Colin Watson  <cjwatson@debian.org>

	sandbox: Work around ESET File Security

	This is a proprietary antivirus program, so this is only a best guess
	from strace output.  The choices are to disable the sandbox entirely or
	to allow a few socket-related system calls if this antivirus program is
	detected, and the latter is probably slightly better.

	Reported by John Sivak.

	* lib/sandbox.c (make_seccomp_filter): If LD_PRELOAD contains the
	substring "/libesets_pac.so", then allow some socket-related system
	calls so that the preload wrapper can talk to its daemon.

	Refactor sandbox attachment to be more composable

	Add fallback pager if the compile-time default is not executable

	A problem with man-db's man is that in the case of the user giving no
	configuration via conf files, argv, or environment variables; man
	defaults to less as pager (PAGER); but less may not be present on the
	system. Sure, other pagers may be selected in aforementioned ways, but
	then the defaults are overridden, making that unsuitable for
	install-time configuration.

	This patch makes man check (if that becomes relevant) if PAGER is
	executable, further defaulting to cat (which is basically ubiquitous,
	being in original Unix, POSIX, and GNU Coreutils) if it is not. Thus
	the poor beginner Unix users without less installed will be able to
	get man pages.

	* src/man.c (sh_lang_first_word): New function.
	(main): Skip configured pager if it is not executable.
	* man/man1/man.man1 (Controlling formatted output, ENVIRONMENT):
	Document fallback to cat.

	Fix preprocessor handling after insertions

	If man has added prefixes to a page to handle such things as disabling
	hyphenation, then it also needs to take account of that when looking for
	a preprocessor line at the start of the page.

	Reported by Bjarni Ingi Gislason.  Fixes Debian bug #867857.

	* src/man.c (get_preprocessors_from_file): Skip over as many blocks
	ending with an .lf macro as there are prefixes.
	(get_preprocessors): Pass the number of prefixes through to
	get_preprocessors_from_file.
	(make_roff_command): Take pp_string as an argument rather than
	dbfilters; callers should now call get_preprocessors themselves.
	(display): Rename seq_ncmds to prefixes.  Call get_preprocessors before
	calling make_roff_command.

	Fix distcheck following cache-owner/setuid changes

	We previously ignored chown failures on "make install", but that's not

	src/tests: Use /tmp for temporary directories

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Eliminate dangerous setgid-root directories

	man-db has created its cache directories as setgid root for nearly 20
	years.  This seems to have originated in https://bugs.debian.org/26002.
	However, this has some dangerous consequences, such as:

	  http://www.halfdog.net/Security/2015/SetgidDirectoryPrivilegeEscalation/

	It seems best to arrange for cache files and directories to be man:man
	rather than man:root.  To do this reliably, as well as adjusting various
	chown and chmod calls, we make man and mandb be setgid man as well as
	setuid man (except in the --disable-setuid case).  This is a much
	simpler and safer solution to the original problem, and doesn't
	introduce any interesting new privilege since the man group's only real
	purpose is to be the man user's primary group and nothing in cache
	directories is group-writeable.

	* configure.ac (AC_CHECK_FUNCS): Add lchown.
	* lib/security.c (init_security): Record initial real and effective
	group IDs as well as user IDs.
	(drop_effective_privs, regain_effective_privs): Update gid.
	* lib/xchown.c (xlchown) [HAVE_LCHOWN]: New function.
	* lib/xchown.c (xlchown) [HAVE_LCHOWN]: Add prototype.
	* m4/man-arg-setuid.m4: Set man_mode to 6755 rather than 4755 in the
	--enable-setuid case.
	* src/Makefile.am (install-exec-hook): Check for man_mode being 6755
	rather than 4755.  Set the group of man and mandb as well as their
	owner.
	* src/check_mandirs.c (chown_if_possible): New function.  This is
	somewhat more careful than previous implementations, changes the group
	as well as the user if possible, and prefers lchown if it is available.
	(mkcatdirs): Drop S_ISGID from cat directories.  Use chown_if_possible.
	(fix_permissions, fix_permissions_tree): New functions to remove setgid
	bit from existing cat directories.
	(testmandirs): Call fix_permissions_tree.
	* src/check_mandirs.h (chown_if_possible): Add prototype.
	* src/man.c (commit_tmp_cat): Set cat file group as well as owner.
	* src/mandb.c (check_chown): Remove.
	(do_chown): Stop taking a uid parameter.  Use chown_if_possible.
	(mandb): Use chown_if_possible for CACHEDIR.TAG.  Set ownership and
	permissions of CACHEDIR.TAG even if it already exists.
	(process_manpath): Set ownership of database files even if they have not
	been changed.

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Make --disable-cache-owner imply --disable-setuid

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Update manual for cache-owner/setuid changes

	* manual/intro.me (Arguments to configure): Add --enable-cache-owner and

	description of --disable-setuid.
	* manual/misc.me (Modes of operation): Add --disable-cache-owner to the
	non-setuid modes.  Mention --enable-setuid rather than
	--enable-setuid=USER.
	* README (Non-generic arguments to configure): Update.

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Allocate dbpaths on the heap rather than the stack

	process_manpath's stack may have gone out of scope by the time cleanup
	functions are called.

	* src/mandb.c (cleanup): Free dbpaths.
	(process_manpath): Allocate dbpaths on the heap.

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Handle cleanup stack more safely

	If push_cleanup was called unexpectedly between a
	push_cleanup/pop_cleanup pair, then the pop_cleanup would remove the
	wrong cleanup function and chaos could ensue.  Avoid this by being more
	precise about which cleanup function should be popped.

	* lib/cleanup.c (pop_cleanup): Take "fun" and "arg" arguments.  Pop the
	topmost matching function from the stack, rather than just the topmost
	function.  Update all callers and prototypes.

	Separate cache owner from --enable-setuid option

	It's useful to have a notion of the cache owner even when man is not
	installed setuid.  --enable-setuid no longer takes an argument, and the
	owner is now set by the --enable-cache-owner option instead.

	* m4/man-arg-cache-owner.m4: New file.
	* m4/man-arg-setuid.m4: Stop accepting an argument.  Only set man_mode,
	not man_owner.
	* configure.ac: Call MAN_ARG_CACHE_OWNER.
	* src/Makefile.am (install-exec-hook): Only chown man and mandb if
	man_mode is 4755 (as well as the existing test for man_owner being
	non-empty).

	Reported by Hanno Boeck.  Fixes Savannah bug #45854.

	man: Avoid dubious use of freopen to reopen base streams

	freopen doesn't actually work properly when base streams have been

2014-11-16  Colin Watson  <cjwatson@debian.org>

	Allow building from git without gnulib-tool

	Since we don't want to keep Gnulib translations in revision control,
	we need gnulib-tool on $PATH when generating the build system in
	order to fetch them, but it's unnecessarily awkward to require
	everyone to have this just in order to build man-db from git.  Allow
	building without this, although it is still required for "make
	dist".

	* configure.ac: No longer issue an error if gnulib/po/Makefile.in.in
	is missing.  Instead, set the Automake conditional HAVE_GNULIB_PO to
	true if and only if gnulib/po/POTFILES.in exists, and only create
	gnulib/po/Makefile.in if gnulib/po/Makefile.in.in exists.

	Don't store canonicalised versions of manpath elements

	We still compare canonicalised versions, but don't store them.
	Storing them results in looking up the wrong catpath in the case
	where one of the configured MANDB_MAP entries is a symlink.

	Broken by commit 01e5a4febfc7b6cd53991455315ae7744c8f31dd; fixes
	Fedora bug #1043401.

	* src/manp.c (create_pathlist): Compare canonicalised versions of

2014-09-16  Colin Watson  <cjwatson@debian.org>

	Don't use pointed-to name as title for database-located pages

	For a pointer record, the pointed-from name is a legitimate alias
	for the located page, and is likely to be closer to the name that
	the user requested.

	Fixes Debian bug #709405.

	* src/man.c (display_database): Don't use the pointed-to name to
	construct the title for display.

	Inspired by a similar change in dpkg.  This takes 'mandb -c' from

2014-09-16  Colin Watson  <cjwatson@debian.org>

	Reorder functions in man to remove need for header file

	man.h was only needed because of some poor function ordering in man.c.
	Reorder functions so that definition comes before use, except in one
	case of mutual recursion.

	* src/man.c (main): Move to end of file.
	(local_man_loop): Move to immediately before man.
	(man): Add a prototype declaration just before local_man_loop, to

	keeping it around.

	* include/manconfig.h.in (FAST_BTREE): Remove commented definition.
	* libdb/db_btree.c (test_insert, gripe_get, dbstore, dblookup):
	Remove.

	* src/tests/Makefile.am (TESTS_ENVIRONMENT): Export STAT_HAS_NSEC to
	tests.
	* src/tests/testlib.sh (next_second): Do nothing if STAT_HAS_NSEC is
	"yes".

2014-09-11  Colin Watson  <cjwatson@debian.org>

	* NEWS: Document this.

2014-09-10  Colin Watson  <cjwatson@debian.org>

	Move database mtime out of the database into file metadata

	This makes the database reproducible between installations, as long
	as the underlying database has predictable behaviour and the set of
	installed manual pages (including their timestamps) remains
	identical.  As a bonus, we now use high-precision times in several
	places.

	Fixes Debian bug #760895.

	* gnulib: Import futimens and timespec modules.
	* libdb/db_btree.c (btree_get_time, btree_set_time): New functions.

	times.
	(update_db_time): Set file modification times rather than updating a
	database row.
	(create_db, purge_missing): Get database file modification times
	rather than fetching a database row.
	(purge_missing): If the new will_run_mandb argument is true, reset
	the database mtime to its value before purging; this ensures that
	mandb will still run as expected afterwards.
	* src/check_mandirs.h (purge_missing): Update prototype.
	* src/mandb.c (xcopy): Copy access and modification times.
	(process_manpath): Work out in advance of purging whether we will
	need to run mandb, and pass that to purge_missing.
	* include/manconfig.h.in (VER_ID): Bump to 2.5.0.
	(KEY): Remove.

	* man/man8/accessdb.man8 (DESCRIPTION), man/it/man8/accessdb.man8
	(DESCRIZIONE): Remove sample output, as it is of limited usefulness
	compared to how awkward it is to maintain, especially in text
	intended for translation.
	* man/po4a/po/man-db-manpages.pot, man/po4a/po/*.po: Update.
	* manual/db.me (Contents of an index database): Remove mention of
	$mtime$.
	(Example database): Remove $mtime$.  Update $version.

	* NEWS: Document this.  Bump version to 2.7.0 to correspond to the
	database version change.

2014-09-09  Colin Watson  <cjwatson@debian.org>

	Make update_db_time static

2014-09-09  Colin Watson  <cjwatson@debian.org>

	Remove unused reset_db_mtime function

	* src/check_mandirs.h (reset_db_mtime): Remove prototype.
	* src/man.c: Stop including "check_mandirs.h".

2014-09-09  Colin Watson  <cjwatson@debian.org>

	Don't purge entries from databases that fail sanity checks

	* src/check_mandirs.c (purge_missing): Return early if
	sanity_check_db fails, for instance in the case of a version
	mismatch.

2014-09-09  Colin Watson  <cjwatson@debian.org>

	Switch away from obsolescent utime function

	POSIX.1-2008 marks utime as obsolescent.  Switch to variants of the
	futimens/utimensat family instead, via Gnulib.  Use higher-precision
	times for cat pages.

	* gnulib: Import stat-time and utimens modules.
	* src/man.c (man_modtime): Change type to struct timespec.
