ChangeLog.1

2015-04-07  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib
	* lib/stddef.in.h: Update from gnulib, incorporating:
	2015-04-02 stddef: port to pre-C11 GCC on x86

2015-04-03  Paul Eggert  <eggert@cs.ucla.edu>

	Port 'configure' to clang 3.5
	* configure.ac: Add -Wno-unknown-attributes if clang;
	otherwise clang 3.5.0 (Fedora 21 x86-64) complains
	"/usr/include/glib-2.0/glib/gmem.h: ... warning: unknown attribute
	'__alloc_size__' ignored".  Use -Werror when checking for -nopie;
	otherwise clang warns about -nopie instead of failing, and then
	later it warns every time the build uses -nopie.

2015-04-03  Ulrich Müller  <ulm@gentoo.org>

	* configure.ac (LD_SWITCH_SYSTEM_TEMACS): Add -nopie option if it
	is supported, in order to avoid segfaults in temacs.  (Bug#18784)

2015-03-27  Pete Williamson  <petewil@chromium.org>  (tiny change)

	Add NaCl target
	* configure.ac: Add a target for Chromium Native Client (NaCl).

2015-03-29  Eli Zaretskii  <eliz@gnu.org>

	* build-aux/dir_top (File): Fix the description of selecting a
	menu item by its number.  (Bug#20213)

2015-03-29  Paul Eggert  <eggert@cs.ucla.edu>

	Fix 'commit-msg' to cite 'CONTRIBUTE'
	As suggested in:
	https://lists.gnu.org/r/emacs-devel/2015-03/msg00947.html
	Also, have the two files match better.
	* CONTRIBUTE: Match what's in build-aux/git-hooks/commit-msg.
	* build-aux/git-hooks/commit-msg: Mention 'CONTRIBUTE'.

2015-03-23  Andreas Schwab  <schwab@suse.de>

2015-03-21  Samer Masterson  <samer@samertm.com>

	* CONTRIBUTE (Test your changes.): New section.
	(Document your changes.): Add doc tips.

2015-03-19  Paul Eggert  <eggert@cs.ucla.edu>

	Better port of pthread usage to FreeBSD
	* configure.ac (ac_func_list): Omit pthread_sigmask, since
	we check for that ourselves rather than relying on gnulib.
	(HAVE_PTHREAD, LIB_PTHREAD): Port better to FreeBSD,
	by also checking for pthread_create, pthread_self, pthread_sigmask.
	Tighten the test for pthread_atfork while we're at it.
	(Bug#20136)

	Merge from gnulib
	This incorporates:
	2015-03-19 fdopendir: port better to MinGW
	2015-03-18 fdopendir: fix typo in comment
	2015-02-24 glob, etc.: port to MSVC v18 on MS-Windows 8.1

	* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.

2015-03-02  Robert Pluim  <rpluim@gmail.com>  (tiny change)

	* configure.ac: Error out if with-file-notification=w32 is
	specified on Cygwin.  (Bug#19909)

2015-02-27  Paul Eggert  <eggert@cs.ucla.edu>

	Don't require GNU putenv
	* configure.ac: Use system putenv even if it lacks GNU features, as
	we don't need them.  This works around a bug in FreeBSD 10.1 getenv.
	(Bug#19874)

2015-02-25  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib

	2015-02-18 getopt: don't crash on memory exhaustion
	2015-02-17 tempname: allow compilation with C++ (trivial)
	2015-02-17 dup2, fcntl: port to AIX
	2015-02-16 getdtablesize, dup2, fcntl: port to Android
	2015-02-11 getdtablesize, signal_h: Fix Android build
	2015-02-11 maint: various whitespace cleanups in tempname

2015-02-13  Jan Djärv  <jan.h.d@swipnet.se>

	* configure.ac: Set locallisppath to empty for NS self contained,
	unless --enable-loadllisppath was given (Bug#19850).

2015-02-09  Paul Eggert  <eggert@cs.ucla.edu>

	* configure.ac (HAVE_LIBXML2): Add missing comma.

2015-02-08  Paul Eggert  <eggert@cs.ucla.edu>

	Port to platforms lacking test -a and -o

	Prefer '&&' and '||' to 'test -a' and 'test -o'.

2015-02-08  Ulrich Müller  <ulm@gentoo.org>

	* configure.ac (--with-gameuser): Default to 'games' group instead
	of 'games' user.

2015-02-04  Paul Eggert  <eggert@cs.ucla.edu>

	* .gitattributes: Ignore blanks at EOL in texinfo.tex.

2015-01-28  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib and try to repair bad merge
	This attempts to repair problems introduced by the bad merge
	5491fd1098d27b3ba3db054076b9ab60fb3558dc.  The easiest way for me
	to fix the badly-merged gnulib files was to run
	'admin/merge-gnulib', so I did that, which also imported the
	following changes:
	* build-aux/update-copyright, m4/gnulib.m4:
	Update from gnulib, incorporating:
	2015-01-15 time: port to MinGW32 3.21
	2015-01-15 update-copyright: apply to self
	2015-01-11 update-copyright: recognize groff's \(co marker

2015-01-28  Eli Zaretskii  <eliz@gnu.org>

	* configure.ac (HAVE_W32): Abort with error message if
	--without-toolkit-scroll-bars was specified.  See
	https://lists.gnu.org/r/emacs-devel/2015-01/msg00525.html
	for the details.

2015-01-27  Paul Eggert  <eggert@cs.ucla.edu>

	Port autogen.sh hook creation to private templates
	* autogen.sh: Do not assume that the hook samples exist.
	This ports to developers who override templatedir in their Git
	configuration.  The downside is that patch applications won't be
	checked, but that's better than autogen.sh failing.
	Problem reported by Sam Steingold in:
	https://lists.gnu.org/r/emacs-devel/2015-01/msg00898.html

2015-01-26  Paul Eggert  <eggert@cs.ucla.edu>

	* INSTALL.REPO: Mention minimum Git version.

2015-01-25  Paul Eggert  <eggert@cs.ucla.edu>

	Use gnustep-config if available
	* configure.ac (--with-gnustep): Document this.
	(NS_GNUSTEP_CONFIG): New variable, set if gnustep-config works.
	If gnustep-config works, use 'gnustep-config --objc-flags' and
	'gnustep-config --gui-libs' to compute GNUstep configuration
	variables, instead of attempting to infer them individually.
	(Bug#19507)

2015-01-21  Ulrich Müller  <ulm@gentoo.org>

	* configure.ac (gamegroup): New AC_SUBST.
	(--with-gameuser): Allow to specify a group instead of a user.
	In the default case, check at configure time if a 'games' user
	exists.

2015-01-16  Paul Eggert  <eggert@cs.ucla.edu>

	Give up on -Wsuggest-attribute=const
	The attribute doesn't help performance significantly, and the
	warning seems to be more trouble than it's worth.  See the thread at:
	https://lists.gnu.org/r/emacs-devel/2015-01/msg00361.html
	* configure.ac (WERROR_CFLAGS): Don't use -Wsuggest-attribute=const.

2015-01-11  Paul Eggert  <eggert@cs.ucla.edu>

	Default to 'configure --enable-silent-rules'
	This greatly shortens the 'make' output, making it more readable
	and useful.  For example, on my platform it shortens a
	4125-character line "gcc -std=gnu99 -c -Demacs -I. -I. -I../lib
	... emacs.c" -- a line so long that it's hard to see what's going
	on or where the diagnostics are -- to just "CC emacs.o".
	* INSTALL: Document this.
	* configure.ac: Add AM_SILENT_RULES([yes]).
	(AM_DEFAULT_VERBOSITY): Remove now-unnecessary initialization.
	(Bug#19501)

2015-01-06  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib
	* lib/stdio.in.h, m4/stdio_h.m4: Update from gnulib, incorporating:
	2015-01-05 stdio: fix use of PRIdMAX on modern mingw

2015-01-04  Paul Eggert  <eggert@cs.ucla.edu>

	* INSTALL: Mention 'make WERROR_CFLAGS='.

	Clarify 'make info'
	* Makefile.in (info): Use GNU make conditional rather than
	an '@' rule with a shell conditional, so that the builder can
	see the submake.

	Less 'make' chatter for VCSWITNESS
	* Makefile.in (dirstate, VCSWITNESS): New macros.
	(src): Use them to lessen 'make' chatter.

2015-01-01  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib, incorporating:
	2015-01-01 version-etc: new year

	* .gitattributes: New file.

	* autogen.sh: Port better to non-GNU 'cp'.  Reported by Han Boetes.

2014-12-31  Paul Eggert  <eggert@cs.ucla.edu>

	Less 'make' chatter at top level
	* Makefile.in (AM_DEFAULT_VERBOSITY, AM_V_GEN, am__v_GEN_)
	(am__v_GEN_0, am__v_GEN_1, AM_V_at, am__v_at_, am__v_at_0)
	(am__v_at_1): New macros, copied from src/Makefile.in.
	($(srcdir)/src/config.in, ${srcdir}/info/dir):
	Be less chatty when not verbose.
	($(srcdir)/src/stamp-h.in): Simplify with '$@'.

2014-12-28  Paul Eggert  <eggert@cs.ucla.edu>

	* build-aux/git-hooks/commit-msg: Allow tabs.
	Treat them as if they were expanded to spaces, with tab stops
	every 8 columns.

2014-12-27  Paul Eggert  <eggert@cs.ucla.edu>

	* .gitignore: Ignore /conftest*.

2014-12-27  Stefan Monnier  <monnier@iro.umontreal.ca>

	* build-aux/git-hooks/commit-msg (at_sign): Bump up line-length limit
	to 78.

2014-12-25  Paul Eggert  <eggert@cs.ucla.edu>

	Prefer stpcpy to strcat.
	* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
	* lib/stpcpy.c, m4/stpcpy.m4: New files, from gnulib.

2014-12-24  Stephen Leake  <stephen_leake@stephe-leake.org>

	* CONTRIBUTE: Move user-level information to doc/emacs/trouble.texi.
	Add Savannah url, cleanup announcing freeze.
	(commit messages): New, gathered from comments on emacs-devel.
	(Changelog notes): Add reference to GNU coding standards section 5.2;
	doc 'present tense', bug fix format.
	(branches): Freeze announcements are made on info-gnu-emacs mailing
	list.
	(git vs rename): New.

2014-12-23  Paul Eggert  <eggert@cs.ucla.edu>

	* lib/gnulib.mk: Regenerate.

2014-12-13  Paul Eggert  <eggert@cs.ucla.edu>

	* .gitignore: Add lib/std*.h, to ignore stdarg.h, stdbool.h, and
	stddef.h.  Remove subsumed entries.
	Add !lib/std*.in.h, so as to not ignore the .in.h files.

2014-12-13  Paul Eggert  <eggert@cs.ucla.edu>

	Port commit-msg to mawk.  Reported by Ted Zlatanov in:
	https://lists.gnu.org/r/emacs-devel/2014-12/msg01093.html
	* build-aux/git-hooks/commit-msg (space, non_space, non_print):
	New vars.  Use them as approximations to POSIX bracket expressions,
	on implementations like mawk that do not support POSIX regexps.

	Improve commit-msg messages and autosquash.
	Reported by Michal Nazarewicz in Bug#19337.
	* build-aux/git-hooks/commit-msg: Add "commit message" to
	diagnostics.  Distinguish better between tabs and other
	unprintable chars in diagnostics.  Don't complain if a prefix
	"fixup! " or "squash! " makes a summary line too long.

2014-12-13  Paul Eggert  <eggert@cs.ucla.edu>

	Port commit-message checking to FreeBSD 9.
	Reported by Jan Djärv in:
	https://lists.gnu.org/r/emacs-devel/2014-12/msg00704.html
	along with some other issues I noticed while testing with FreeBSD.
	* build-aux/git-hooks/commit-msg: Prefer gawk if available.
	Prefer en_US.UTF-8 to en_US.utf8, as it's more portable.
	Work around bug in FreeBSD 9 awk, where /[[:cntrl:]]/ matches
	ordinary text characters.
	Be less tricky about quoting "'" in a shell script.

2014-12-13  Stefan Monnier  <monnier@iro.umontreal.ca>

	* .gitignore: Ignore autosave files.

2014-12-12  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib.
	2014-12-12 stddef: support C11's max_align_t

	from admin/notes/* here.

	* INSTALL.REPO: You can't "just run make" after a clean checkout.

2014-12-05  Stephen Leake  <stephen_leake@stephe-leake.org>

	* CONTRIBUTE: Move here from etc/, preparatory to further
	changes/cleanup.

2014-12-05  Paul Eggert  <eggert@cs.ucla.edu>

	* .gitignore: Remove redundant pattern (subsumed by _*).
	Avoid "**", as it requires Git 1.8.2 or later.

2014-12-05  Eli Zaretskii  <eliz@gnu.org>

	* .gitignore: Ignore test/biditest.txt.

2014-12-01  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* .gitignore: Ignore loaddefs directly under lisp, and in
	sub-sub-directories.

2014-11-29  Paul Eggert  <eggert@cs.ucla.edu>

	Add more of the old .bzrignore to .gitignore.
	Plus a few more .gitignore improvements.
	* .gitignore: Add copyright notice, since it's big enough.
	Put exceptions immediately after the patterns they're exceptions
	to, to make them easier to follow.
	Give four exceptions for the Makefile pattern.
	Ignore /confdefs.h, test/indent/*.new, TAGS, GPATH, GSYMS, GRTAGS,
	GTAGS, ID, *.exe, some nextstep-related files,
	jisx2131-filter, *.orig, *.rej, etc/emacs.tmpdesktop, *.in-h
	_* (except for build-aux/snippet/_Noreturn.h), /bin/, /BIN/,
	/data/, etc/icons/, lib/cxxdefs.h, lib/SYS/, /libexec/, /lock/,
	/README.W32, /share/, /site-lisp/, src/gdb.ini, /var/.
	Ignore /configure.lineno, since POSIX requires
	LINENO only with the User Portability Utilities option.
	Ignore *cust-load.el and *loaddefs.el only under lisp.
	Ignore core files of various flavors.
	Do not ignore etc/refcards/gnus-logo.pdf.

2014-11-29  Eli Zaretskii  <eliz@gnu.org>

	created by the MS-DOS build.

	Restore 'Bug#' -> 'debbugs:' rewrite in log-edit-mode.
	* .dir-locals.el (log-edit-mode): Restore the (log-edit-rewrite-fixes
	"[ \n](bug#\\([0-9]+\\))" . "debbugs:\\1").  See Glenn Morris in:
	https://lists.gnu.org/r/emacs-devel/2014-11/msg01187.html

	Simplify and fix doc-related .gitignore files.
	This fixes some unwanted 'git status' output after 'make docs'.
	* .gitignore: Add **/Makefile, **/makefile.
	Remove Makefile, makefile.
	Add doc/*/*.xxx rules for the usual kinds of documentation outputs
	and temporaries.  Add doc/misc/cc-mode.ss.
	* doc/emacs/.gitignore, doc/lispintro/.gitignore, doc/misc/.gitignore:
	* lwlib/.gitignore, oldXMenu/.gitignore:
	Remove, as these .gitignore files are no longer needed.

2014-11-26  Dani Moncayo  <dmoncayo@gmail.com>

	* configure.ac [MINGW]: Fix the way of getting the right host
	platform.

2014-11-25  Glenn Morris  <rgm@gnu.org>

	* configure.ac: Fix yesterday's use of uninitialized $version.

2014-11-25  Oscar Fuentes  <ofv@wanadoo.es>

	* configure.ac [MINGW]: Set $canonical default value as per the
	compiler's target.

2014-11-24  Glenn Morris  <rgm@gnu.org>

	* configure.ac [HAVE_W32]: Generate nt/*.rc files when HAVE_W32,
	not just when using mingw32.

2014-11-22  Glenn Morris  <rgm@gnu.org>

	Further reduce number of versioned files storing Emacs version number.
	* configure.ac (comma_version, comma_space_version) [mingw32]:
	New output variables.
	(nt/emacs.rc, nt/emacsclient.rc) [mingw32]: New output files.
	* make-dist: Update nt/ for *.rc -> *.rc.in changes.

2014-11-19  Dani Moncayo  <dmoncayo@gmail.com>

	* build-aux/msys-to-w32: Simplify implementation and docstring;
	Paths starting with '%emacs_dir%' are just considered relative.

2014-11-16  Christoph Scholtes  <cschol2112@gmail.com>

	* .gitignore: Ignore generated file lib/stdalign.h.

2014-11-16  Eli Zaretskii  <eliz@gnu.org>

	* .gitignore: Add more ignorables.

2014-11-14  Andreas Schwab  <schwab@linux-m68k.org>

	* Makefile.in (config.status): Don't depend on
	${srcdir}/lisp/version.el.

2014-11-14  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib.
	2014-11-14 extern-inline: update commentary about GCC bugs
	2014-11-06 unistd: port to iOS
	2014-11-04 update from texinfo
	* doc/misc/texinfo.tex, lib/unistd.in.h, m4/extern-inline.m4:
	Update from gnulib.

	build: port to GCC 4.6.4 + glibc 2.5
	On platforms this old, building with _FORTIFY_SOURCE equal to 2
	results in duplicate definitions of standard library functions.
	Reported by Nelson H. F. Beebe.
	* configure.ac (_FORTIFY_SOURCE): Sort after GNULIB_PORTCHECK.
	By default, do not enable this unless GNULIB_PORTCHECK is defined.
	This better matches the original intent, which as I recall was to
	enable these extra checks only with --enable-gcc-warnings.

2014-11-14  David Reitter  <david.reitter@gmail.com>

	* Makefile.in (install-arch-indep): Compress publicsuffix.txt file.

	* .gitignore: Copy over sufficient ignorable files from the old
	.bzrignore that a simple build doesn't list lots of unregistered files.

2014-11-11  Eric S. Raymond  <esr@thyrsus.com>

	Git transition.
	* Makefile.in (src): Set VCSWITNESS appropriately for git.

	All bzr revision IDS, and all CVS revision IDs for which a commit
	could be identified, were changed to time-date!committer version
	stamps. All .cvsignore files in the history became .gitignore
	files. Fixes-bug annotations from bzr were copied into the
	corresponding commit comments.

	(The first .cvsignore commit was 1999-09-30T14:07:54Z!fx@gnu.org.
	The last CVS commit was 2009-12-27T08:11:12Z!cyd@stupidchicken.com.)

	Committer/author email addresses are generally correct for the
	transition day, not necessarily when the commit was originally made.

2014-11-10  Glenn Morris  <rgm@gnu.org>

	interface, and the implementation.
	* Makefile.in (epaths-force-w32): Update for the above.  Also
	simplify, assuming that the shell is bash (which is the case in MSYS).
	(msys_w32prefix_subst, msys_sed_sh_escape): Remove (no longer used).

2014-11-05  Glenn Morris  <rgm@gnu.org>

	Fix race in 'make info/dir', and speed it up.
	* Makefile.in (AWK, srcdir_doc_info_dir_inputs, info_dir_inputs):
	New macros.
	(clean): Remove info-dir.*.
	(info_dir_deps): Depend on make-info-dir too.
	(${srcdir}/info/dir): Make sure info directory exists.
	Don't call pwd; just redirect make-info-dir's stdout to temp file.
	* build-aux/make-info-dir: Send output to stdout.
	Take input file names from args.
	Fix a "FIXME inefficient looping" by using awk's associative arrays.
	Basically, this rewrites the script from scratch, and speeds up
	'make info/dir' from 2.6s to 0.07s on my platform.

2014-10-20  Glenn Morris  <rgm@gnu.org>

	* Merge in all changes up to 24.4 release.

	Fix putenv race conditions that can crash Emacs (Bug#8705).
	* configure.ac (LOCALTIME_CACHE): Remove.
	We needn't worry about SunOS 4 any more; Sun dropped support in 2003.
	All uses of LOCALTIME_CACHE removed.  This simplifies the fix.
	(tzalloc): Add check for this function.

2014-10-06  Jan Djärv  <jan.h.d@swipnet.se>

	* README: Bump version to 25.0.50.

	* configure.ac (AC_INIT): Bump version to 25.0.50.

2014-09-29  Dmitry Antipov  <dmantipov@yandex.ru>

	* configure.ac: Assume verbose output for older Automake.

2014-09-04  Paul Eggert  <eggert@cs.ucla.edu>

	* configure.ac (MAKEINFO): Clean up some configuration bitrot.
	MAKEINFO is already set before we get here, so no need to call AC_PATH_PROG.
	Bypass $am_missing_run.  Simplify version-number checking.

2014-09-02  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib, incorporating:

	* configure.ac (MAKE): Export it, for config.status.
	Needed on AIX when 'configure' infers MAKE=gmake.
	(__restrict_arr): Remove; no longer used.

2014-08-30  Paul Eggert  <eggert@cs.ucla.edu>

	Vector-sorting fixes (Bug#18361).
	* configure.ac (qsort_r): Remove, as we no longer use qsort-like
	functions.
	* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
	* lib/vla.h, m4/vararrays.m4: New files, copied from gnulib.
	* lib/stdlib.in.h, m4/stdlib_h.m4: Sync from gnulib, incorporating:
	2014-08-29 qsort_r: new module, for GNU-style qsort_r
	The previous two files' changes are boilerplate generated by
	admin/merge-gnulib, and should not affect Emacs.

2014-08-29  Dmitry Antipov  <dmantipov@yandex.ru>

	* configure.ac (AC_CHECK_FUNCS): Check for qsort_r.

2014-08-28  Ken Brown  <kbrown@cornell.edu>

	* Makefile.in (appdatadir): New variable.
	(install-etc, uninstall, clean): Handle etc/emacs.appdata.xml.

2014-08-23  Karol Ostrovsky  <karol.ostrovsky@gmail.com>  (tiny change)

	* configure.ac: Accept "*-mingw*", not just "*-mingw32", as
	canonical name of a MinGW build, because using MSYS2 'uname'
	produces "MINGW64".

2014-08-21  Ken Brown  <kbrown@cornell.edu>

	* configure.ac (HAVE_XPM): Explain the use of CPPFLAGS in the
	Cygwin-w32 build.  (Bug#18302)

2014-08-11  Paul Eggert  <eggert@cs.ucla.edu>

	Don't prevent random file systems from being unmounted (Bug#18232).
	This fix relies on having the 'fchdir' function, and on having
	"." be searchable (or at least readable, on platforms lacking O_SEARCH),
	but that's good enough to handle the vast majority of cases and the
	remaining folks can just live with the annoyance of file systems
	that occasionally can't be unmounted.
	* configure.ac (fchdir): New function to check for.
	* lib/save-cwd.c: Copy from gnulib, except omit the part that
	allocates memory, since that can cause problems in Emacs.
	* lib/save-cwd.h: Copy from gnulib.

2014-08-10  Eli Zaretskii  <eliz@gnu.org>

	* config.bat: Fix some confusing wording.

	* config.bat: Require DJGPP 2.02 or later.

2014-08-09  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib, incorporating:
	2014-08-07 getdtablesize: fall back on sysconf (_SC_OPEN_MAX)
	2014-08-05 sys_select: fix FD_ZERO problem on Solaris 10
	* lib/getdtablesize.c, lib/sys_select.in.h: Update from gnulib.

2014-08-07  Reuben Thomas  <rrt@sc3d.org>

	* README: ``MSDOG'' becomes ``MS-DOS''.

2014-08-04  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib, incorporating:
	2014-08-04 extern-inline: port to FreeBSD, DragonFly
	* lib/gnulib.mk: Regenerate (comment change only).
	* m4/extern-inline.m4: Update from gnulib.

2014-08-02  Paul Eggert  <eggert@cs.ucla.edu>

	* configure.ac (HAVE_TIMERFD): Also check for TFD_NONBLOCK,
	since the code is using TFD_NONBLOCK now.

2014-07-31  Paul Eggert  <eggert@cs.ucla.edu>

	Simplify timerfd configuration and fix some minor glitches.
	* configure.ac (HAVE_TIMERFD): Define only if TFD_CLOEXEC works,
	since the code leaked file descriptors to children when !TFD_CLOEXEC.
	(HAVE_TIMERFD_CLOEXEC): Remove; no longer used.
	* m4/clock_time.m4 (gl_CLOCK_TIME): Don't check for clock_getres.
	This reverts the previous change to this file, so it matches
	gnulib again.

2014-07-28  Dmitry Antipov  <dmantipov@yandex.ru>

	* configure.ac (toplevel): Check whether GNU/Linux-specific
	timerfd functions and macros are available.
	* m4/clock_time.m4 (gl_CLOCK_TIME): Check for clock_getres as well.

2014-07-13  Paul Eggert  <eggert@cs.ucla.edu>

	Improve behavior of 'bzr up; cd src; make -k'.
	* Makefile.in (ACLOCAL_INPUTS): Add all m4/*.m4 files.

2014-07-12  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib, incorporating:

	* lib/mktime.c: Update from gnulib.

	* Makefile.in (install-arch-indep): Avoid readdir race (Bug#17971).

2014-07-10  Dmitry Antipov  <dmantipov@yandex.ru>

	* configure.ac: Check whether sys/sysinfo.h provides
	Linux 'sysinfo' function and 'struct sysinfo' type.

2014-06-28  Glenn Morris  <rgm@gnu.org>

	* configure.ac (lwlib_deps_frag, oldxmenu_deps_frag): New output files.
	* make-dist (lwlib, oldXMenu): Distribute *.mk.

2014-06-27  Glenn Morris  <rgm@gnu.org>

	* Makefile.in (src): No more need to pass BOOTSTRAPEMACS.

	* make-dist: Exclude test/automated/*.log.

2014-06-26  Glenn Morris  <rgm@gnu.org>

	* Makefile.in (mostlyclean, clean): Maybe clean test/automated.

2014-06-21  Paul Eggert  <eggert@cs.ucla.edu>

	* configure.ac: Warn about --enable-link-time-optimization's issues
	in --help message (Bug#17806).

	Port to GCC 4.9.0 with link time optimization (Bug#17806).
	* configure.ac (CFLAGS): With link time optimization,
	use -ffat-lto-objects if supported; otherwise Emacs won't
	build with GCC 4.9.0.

2014-06-20  Paul Eggert  <eggert@cs.ucla.edu>

	Diagnose failures due to colons in directory names (Bug#17278).
	* Makefile.in (epaths-force): Don't allow ':' in directories whose
	names go into a colon-separated path.
	* configure.ac: Fail if submake fails.

2014-06-17  Paul Eggert  <eggert@cs.ucla.edu>

	Omit redundant extern decls.
	Most of this patch is from Dmitry Antipov, in:
	https://lists.gnu.org/r/emacs-devel/2014-06/msg00263.html
	* configure.ac (WERROR_CFLAGS): Add -Wredundant-decls.

	Merge from gnulib, incorporating:
	2014-06-17 acl: port to gcc -Wredundant-decls
	2014-06-01 gnulib-common.m4: Fix typo in _GL_UNUSED_LABEL.
	* lib/acl.h, m4/gnulib-common.m4: Update from gnulib.

2014-06-15  Glenn Morris  <rgm@gnu.org>

	* Makefile.in: Use `make -C' rather than `cd && make' throughout.

	* Makefile.in: Parallelize clean rules using GNU make features.
	(submake_template): New definition.
	(mostlyclean_dirs, clean_dirs, distclean_dirs, maintainer_clean_dirs):
	New variables.
	(mostlyclean, clean, distclean, bootstrap-clean, maintainer-clean)
	(extraclean): Define using each subdirectory as a prequisite.
	* lib/Makefile.am (bootstrap-clean): New.

2014-06-15  Paul Eggert  <eggert@cs.ucla.edu>

	Port part of the AIX fix to Solaris (Bug#17598).
	* configure.ac (_REENTRANT): Define on Solaris if HAVE_PTHREAD.
	This ports part of the recent AIX fixes to Solaris.  It is needed
	for the same reason that _THREAD_SAFE is needed on AIX, e.g., to
	make sure that each thread has its own 'errno'.

2014-06-13  Glenn Morris  <rgm@gnu.org>

	* Makefile.in (CC, CFLAGS, LDFLAGS, CPPFLAGS, abs_top_srcdir):
	Remove, no longer used.
	(lib, lib-src, lisp, nt, src, blessmail, install-arch-dep)
	(install-nt, install-strip, uninstall, uninstall-nt)
	(mostlyclean, clean, distclean, bootstrap-clean)
	(maintainer-clean, extraclean, TAGS, tags, check, $(DOCS)):
	($(INSTALL_DOC), $(UNINSTALL_DOC), info, bootstrap, check-declare):
	GNU make automatically passes command-line arguments to sub-makes.

2014-06-11  Paul Eggert  <eggert@cs.ucla.edu>

	Use a shell function in configure.ac to cut down on code duplication.
	* configure.ac (emacs_check_gnu_make): New shell function.
	Use it to avoid duplication when checking for GNU Make.
	It's OK for 'configure' to use shell functions these days,
	as long as we follow the advice in the 'Shell Functions'
	section of the Autoconf manual.

2014-06-11  Glenn Morris  <rgm@gnu.org>

	* configure.ac: Require at least version 3.81 of GNU make.

2014-06-10  Paul Eggert  <eggert@cs.ucla.edu>

	Rely on AC_CANONICAL_HOST to detect whether we're using mingw.
	See the thread containing:
	https://lists.gnu.org/r/emacs-devel/2014-06/msg00206.html
	* configure.ac (AC_CANONICAL_HOST): Invoke this as early as we
	can, which is just after AM_INIT_AUTOMAKE.  Then check for mingw
	just after that.

2014-06-10  Glenn Morris  <rgm@gnu.org>

	* Makefile.in (AUTOCONF, AUTOMAKE, AUTOHEADER, ACLOCAL):
	New, set by configure.  Use throughout where appropriate.

	* Makefile.in (INFO_EXT): Remove and replace by ".info" throughout.
	* configure.ac (INFO_EXT, INFO_OPTS): Remove output variables.

2014-06-08  Paul Eggert  <eggert@cs.ucla.edu>

	Port better to AIX (Bug#17598).
	* configure.ac (with_xpm_set): New shell var.
	(_THREAD_SAFE): Define on AIX if HAVE_PTHREAD.
	(with_xpm): Default to 'no' on AIX.
	(LIBXPM): Append -lXpm if -lXaw is also used, as the latter
	requires the former on AIX.

2014-06-05  Paul Eggert  <eggert@cs.ucla.edu>

	Try harder to find GNU Make when configuring.
	* configure.ac (AC_PROG_MAKE_SET): Define a dummy.
	(MAKE): Set it to GNU Make, if one can be found.
	Search PATH for 'make', 'gmake', 'gnumake'.
	This works better on platforms like AIX, where GNU Make
	might be in /opt/freeware/bin/make, and reside
	behind /usr/bin/make in the PATH.

2014-06-05  Dmitry Antipov  <dmantipov@yandex.ru>

	* configure.ac (POLL_FOR_INPUT): Define with HAVE_WINDOW_SYSTEM.
	* INSTALL: Mention SVG image support.

2014-06-05  Paul Eggert  <eggert@cs.ucla.edu>

	* configure.ac: --without-all now implies --without-xft, --disable-acl.

	* configure.ac (C_HEAP_SWITCH): Remove.

2014-06-02  Paul Eggert  <eggert@cs.ucla.edu>

	Fix port to 32-bit AIX with xlc (Bug#17598).
	This doesn't fix Bug#17598, but it does fix a regression since Emacs
	built with xlc until recently, and perhaps it'll help us fix Bug#17598.
	* configure.ac (GC_SETJMP_WORKS): Define for AIX, too.
	Merge from gnulib, incorporating:
	2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1
	* lib/ftoastr.c: Update from gnulib.

2014-06-01  Paul Eggert  <eggert@cs.ucla.edu>

	2014-06-01 gnulib-common.m4: add _GL_UNUSED_LABEL
	2014-05-31 dup2, fcntl, fcntl-h: port to AIX 7.1
	2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1
	* lib/acl-internal.h, lib/fcntl.in.h, lib/ftoastr.h:
	* m4/dup2.m4, m4/fcntl.m4, m4/gnulib-common.m4:
	Update from gnulib.

2014-06-01  Juanma Barranquero  <lekktu@gmail.com>

	* configure.ac (C_HEAP_SWITCH): Raise HEAPSIZE value for 32-bit
	builds on Windows.

2014-05-29  Paul Eggert  <eggert@cs.ucla.edu>

	* configure.ac (pthread_sigmask): Look in LIB_PTHREAD too (Bug#17561).
	Fixes configuration glitch found in <https://bugs.gnu.org/17561#59>.

2014-05-29  Eli Zaretskii  <eliz@gnu.org>

	* configure.ac (ADDSECTION, TEMACS_POST_LINK): Don't compute,
	unused.

2014-05-29  Paul Eggert  <eggert@cs.ucla.edu>

	Don't substitute sigprocmask for pthread_sigmask (Bug#17561).
	sigprocmask isn't portable in a multithreaded process.
	* configure.ac (gl_THREADLIB): Remove dummy.
	Merge from gnulib, incorporating:
	2014-05-28 pthread_sigmask, timer-time: use gl_THREADLIB only if needed
	* m4/pthread_sigmask.m4, m4/timer_time.m4: Update from gnulib.

2014-05-29  Glenn Morris  <rgm@gnu.org>

	* configure.ac: Explicitly drop some ancient Solaris versions.

2014-05-27  Fabrice Popineau  <fabrice.popineau@gmail.com>

	* configure.ac (C_HEAP_SWITCH): Define for different values of
	dumped heap size depending on 32/64bits arch on Windows.
	Don't check for pthreads.h on MinGW32/64, it gets in the way.
	Use mmap(2) for buffers and system malloc for MinGW32/64.
	(EMACS_HEAPSIZE): Remove.

2014-05-27  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib, incorporating:
	2014-05-21 fchdir: port 'open' and 'close' redefinitions to AIX 7.1
	* lib/openat-proc.c: Update from gnulib.

2014-05-26  Paul Eggert  <eggert@cs.ucla.edu>

	Fix port to 32-bit AIX (Bug#17540).
	* configure.ac (opsys): On Power Architecture, treat release 7 of
	AIX like releases 5 and 6.

2014-05-19  Paul Eggert  <eggert@cs.ucla.edu>

	Remove dependencies on getdelim and getline.
	* configure.ac (getdelim, getline): Remove.

2014-05-18  Glenn Morris  <rgm@gnu.org>

	* configure.ac: Do not bother testing for png in non-graphical builds.

2014-05-18  Paul Eggert  <eggert@cs.ucla.edu>

	Port ctags+etags build to Sun C 5.12.
	* .bzrignore: Remove lib-src/ctags.c.

	Port recent libpng changes to hosts with missing png.h.
	* configure.ac (HAVE_PNG): Port to platforms where libpng-config
	succeeds but png.h is absent, by testing libpng-config's output
	rather than trusting it.  I ran into this problem when building
	Emacs trunk on a Solaris 10 host.

2014-05-17  Paul Eggert  <eggert@cs.ucla.edu>

	Assume C99 or later (Bug#17487).
	* lib/stdarg.in.h, lib/stdbool.in.h, m4/stdarg.m4, m4/stdbool.m4:
	Remove.
	* configure.ac (_AC_PROG_CC_C89): Define a dummy, to keep 'configure'
	smaller.
	(gl_PROG_CC_C99): Use this to get C99 or later.
	* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.

2014-05-16  Paul Eggert  <eggert@cs.ucla.edu>

	Don't require pkg-config when building from repository.
	* INSTALL: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.
	* INSTALL.REPO: pkg-config is no longer required to build from
	the repository.
	* autogen.sh: Don't check for pkg-config.
	(progs): Remove pkg-config.
	(pkg_config_min, AUTORECONF_ENV, env_space, ACLOCAL_PATH):
	Remove.  All uses removed.
	* m4/pkg.m4: New file, built by admin/merge-pkg-config.
	* configure.ac: Remove unnecessary m4_pattern_forbid of ^PKG_ and
	an AC_ARG_VAR of PKG_CONFIG_PATH.  pkg.m4 does that for us.
	(EMACS_CHECK_MODULES): Remove workaround for old pkg-config bug,
	as we use pkg.m4 from a newer pkg-config.

2014-05-15  Jan Djärv  <jan.h.d@swipnet.se>

	* configure.ac (LIBPNG): Do not test for libpng if NS_IMPL_COCOA.

2014-05-13  Dmitry Antipov  <dmantipov@yandex.ru>

	* configure.ac (HAVE_XFIXES): Define if available.
	(XFIXES_CFLAGS, XFIXES_LIBS): New AC_SUBSTs.
	(--enable-link-time-optimization): Add clang support.
	* INSTALL: Mention it.

2014-05-12  Katsumi Yamaoka  <yamaoka@jpl.org>

	* configure.ac (EMACS_CHECK_MODULES): Fix typo in previous change.

2014-05-11  Paul Eggert  <eggert@cs.ucla.edu>

	Work around bug in pkg-config before 0.26 (Bug#17438).
	* configure.ac (EMACS_CHECK_MODULES): Check for failed exit status
	of pkg-config, on older pkg-config versions that don't do it
	properly.

2014-05-07  Glenn Morris  <rgm@gnu.org>

	* autogen.sh: Check for failing aclocal.

2014-05-05  Glenn Morris  <rgm@gnu.org>

	* autogen.sh: Check any pre-existing ACLOCAL_PATH.

2014-05-04  Paul Eggert  <eggert@cs.ucla.edu>

	Consult libpng-config more consistently (Bug#17339).
	This is mainly for simplicity, but it should also avoid
	some future problems like the ones we recently had with NetBSD.
	* configure.ac (LIBPNG): Configure after LIBZ.  Use libpng-config
	for cflags, too.  Append -lz if we're not already doing that with
	LIBZ.  Do not bother appending -lm, since we always append that.
	Coalesce some duplicate code.

	* autogen.sh: Use ‘"’ to quote a message that often contains ‘'’.

	Require ImageMagick >= 6.3.5, due to PixelSetMagickColor (Bug#17339).
	* configure.ac (IMAGEMAGICK_MODULE): Bump prereq from 6.2.8 to 6.3.5.
	A more-complicated fix would be to remove uses of PixelSetMagickColor,
	introduced in ImageMagick 6.3.5 (Sept. 2007).

2014-05-04  Glenn Morris  <rgm@gnu.org>

	* configure.ac (LIBPNG): Consult libpng-config for the precise
	form of "-lpng" to use.  (Bug#17339)

2014-05-03  Glenn Morris  <rgm@gnu.org>

	* autogen.sh: If all else fails, try using pkg-config to find pkg.m4.

2014-05-03  Paul Eggert  <eggert@cs.ucla.edu>

	Get --enable-gcc-warnings to work after touching configure.ac.
	Preserve ACLOCAL_PATH in later builds, so that by default it has
	the same value as it did in the first build after initial checkout.
	* Makefile.in (ACLOCAL_PATH): New macro.
	($(srcdir)/aclocal.m4): Use it.
	* configure.ac (ACLOCAL_PATH): AC_SUBST it.
	* autogen.sh (env_space): New var.
	Tell user what variables, if any, to pass to 'configure'.

	Get --enable-gcc-warnings working again.
	The recent changes to configure.ac removed the transliteration of
	-I to -isystem in CFLAGS, which is needed for --enable-gcc-warnings.
	Bring this back while keeping the spirit of the recent changes.
	* configure.ac (edit_cflags): Restore this shell var, and put it
	at the top level, where it'll be useful when emacs-24 is next merged.
	(EMACS_CHECK_MODULES): New macro.  All uses of PKG_CHECK_MODULES
	changed to use it.

	Make it easier on maintainers who use their own Automake.
	* autogen.sh (ACLOCAL_PATH, AUTORECONF_ENV): New vars.
	Set them to avoid problems when maintainers prepend their own
	Automake installations to their PATH.  Report an error if pkg.m4
	can't be found.

2014-05-02  Glenn Morris  <rgm@gnu.org>

	* configure.ac (PKG_CONFIG_PATH): Declare with AC_ARG_VAR.

	* configure.ac (--with-pkg-config-prog): Remove.
	Use the PKG_CONFIG environment variable instead if you need it.

	* configure.ac: Use pkg-config's pkg.m4, rather than reinventing it.
	Add explicit AC_SUBST's where needed.
	* autogen.sh (progs): Add pkg-config.
	(pkg_config_min): New variable.

	* configure.ac (AC_CONFIG_MACRO_DIR): Use it.

	* autogen.sh (get_version): Handle no leading whitespace.
	(check_version, main): Handle program names with hyphens.

2014-04-30  Glenn Morris  <rgm@gnu.org>

	* configure.ac: Treat MirBSD as OpenBSD.  (Bug#17339)

2014-04-21  Daniel Colascione  <dancol@dancol.org>

	* .bzrignore: Add a.out to bzr ignore list (a test generates this
	file).

2014-04-19  Paul Eggert  <eggert@cs.ucla.edu>

	Link to glib-using libraries when checking for glib (Bug#17289).
	* configure.ac (XGSELOBJ): Include GTK_LIBS, RSVG_LIBS, etc.
	when testing whether Glib is linked in.  Similarly for CFLAGS.
