* configure.in (INSTALL_INFO): Set it with one call to
AC_PATH_PROG, not three.
(PKG_CONFIG): Hoist this out of PKG_CHECK_MODULES, since it's
so likely that it'll be needed.
(AC_CHECK_HEADERS_ONCE): Prefer to AC_CHECK_HEADERS where either works.
(AC_PROG_MAKE_SET): Remove; Automake does this.
(sysinfo): Do not check for this function, as it's never used.
(tzset): Check for this function just once.
* admin/CPP-DEFINES: Remove HAVE_SYSINFO.
* m4/manywarnings.m4: Sync from gnulib, incorporating the following:
2012-05-27 manywarnings: remove duplicate -Wmultichar entry
Previously the file was named m4/gl-comp.m4 due to DOS 8+3 restrictions,
even though the file's name in gnulib is m4/gnulib-comp.m4.
This had a problem when merging from gnulib, as the code temporarily
renamed it to the full name, causing problems when interrupted.
Now the file has its full name, with the idea that we will find
a solution for MS-DOS that does not affect the rest of Emacs.
* m4/gnulib-comp.m4: Rename from m4/gl-comp.m4.
* admin/merge-gnulib: Leave m4/gnulib-comp.m4's name alone.
dated 2011-10-07. Regenerating from current gnulib would be a
pervasive change, and currently the trunk isn't open to such changes.
* configure.in (WARN_CFLAGS): Remove; no longer needed now
that gnulib does it.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
I have been using this change for many months in my private copy
of Emacs, and have used it to find several bugs. It's mature
enough to publish now.
* Makefile.in (GNULIB_MODULES): Add warnings, manywarnings.
* configure.in: Support --enable-gcc-warnings, in the style of
other GNU packages such as coreutils.
(C_WARNINGS_SWITCH): Remove, replacing with...
(WARN_CFLAGS, GNULIB_WARN_CFLAGS): New variable.
(PKG_CHECK_MODULES, C_SWITCH_X_SITE): Use -isystem rather than -I,
when including system files with GCC.
* etc/NEWS: Mention --enable-gcc-warnings.
* lib/Makefile.am (AM_CFLAGS): New macro.
* m4/manywarnings.m4, m4/warnings.m4: New files, from gnulib.
* lib-src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(BASE_CFLAGS): Use new macros rather than old.
* lwlib/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* oldXMenu/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
* src/regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
-Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
-Wunused-result, -Wunused-variable. This should go away once
the Emacs and Gnulib regex code is merged.
(xmalloc, xrealloc): Now static.
Bug reported by Chong Yidong for SunOS 5.10 Generic_127111-11 sparc.
I cannot reproduce it on SunOS 5.10 Generic_141444-09 sparc but
possibly this is because Sun fixed the 'stat' bug in my version.
* Makefile.in (GNULIB_TOOL_FLAGS): Do not avoid the pathmax module.
* lib/pathmax.h, m4/pathmax.m4: New files, from gnulib.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
These changes are based on gnulib version
4f11d6bebc3098c64ffde27079ab0d0cecfd0cdc dated 2011-10-07 20:59:10,
because Emacs is in feature freeze and we do not want to merge any
more-recent changes from gnulib.
* lib/signal.in.h, lib/sigprocmask.c, m4/gl-comp.m4:
* m4/gnulib-common.m4: Merge from gnulib.
Without this, 'configure' would say "func_gl_gnulib_m4code_pathmax:
command not found" on powerpc-apple-darwin9.8.0.
This clarifies and fixes some licensing issues raised by Glenn Morris
<http://lists.gnu.org/archive/html/bug-gnulib/2011-09/msg00397.html>.
It also merges the latest version of texinfo.tex and has some
MSVC-related changes that don't affect Emacs.
* Makefile.in (GNULIB_TOOL_FLAGS): Avoid msvc-inval, msvc-nothrow,
pathmax, and raise, since these are needed only to address
MSVC-related issues that Emacs doesn't have.
* doc/misc/texinfo.tex, lib/dup2.c, lib/gnulib.mk, lib/signal.in.h:
* lib/sigprocmask.c, lib/stat.c, lib/stdio.in.h, lib/sys_stat.in.h:
* lib/unistd.in.h, m4/dup2.m4, m4/getloadavg.m4, m4/gl-comp.m4:
* m4/include_next.m4, m4/signal_h.m4, m4/signalblocking.m4:
* m4/stdint.m4, m4/stdio_h.m4, m4/sys_stat_h.m4, m4/time_h.m4:
* m4/unistd_h.m4: Merge from gnulib.
* lib/lstat.c, lib/stat.c, m4/include_next.m4, m4/nocrash.m4:
* m4/signal_h.m4, m4/time_h.m4, m4/unistd_h.m4:
Merge from gnulib. This fixes a compilation error on Tru64 UNIX
aka OSF/1 5.1 DTK cc. There is also some mingw stuff here that
doesn't affect Emacs.
* m4/largefile.m4: New file, so that Emacs does not mess up when
accessing files with large inode numbers in MacOS X 10.5 and later.
* m4/nocrash.m4: New file, to avoid triggering background debugger
and/or create core dumps during 'configure'.
* build-aux/move-if-change: Renamed from move-if-change.
* build-aux/snippet/arg-nonnull.h: Renamed from arg-nonnull.h.
* build-aux/snippet/c++defs.h: Renamed from c++defs.h.
* build-aux/snippet/warn-on-use.h: Renamed from warn-on-use.h.
* build-aux/snippet/_Noreturn.h: New file, for draft C1X _Noreturn.
* .bzrignore: The autogenerated files compile, config.guess,
config.sub, depcomp, install-sh, and missing are now in build-aux.
* Makefile.in (epaths-force, sync-from-gnulib):
move-if-change is now in build-aux.
(GNULIB_TOOL_FLAGS): Avoid threadlib; this is now a prerequisite
of gnulib's pthread_sigmask module, but Emacs doesn't need it.
(mkdir): install-sh is now in build-aux.
* config.bat: c++defs.h is now in build-aux/snippets.
* configure.in: Specify AC_CONFIG_AUX_DIR with build-aux (the
usual parameter).
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
* lib/makefile.w32-in (ARG_NONNULL_H): arg-nonnull.h moved
to build-aux/snippet.
* lib/pthread_sigmask.c, lib/stdlib.in.h, m4/extensions.m4:
* m4/getopt.m4, m4/gnulib-common.m4, m4/pthread_sigmask.m4:
Merge from gnuilib. This fixes porting bugs on Cygwin, Irix, and
Solaris, enables MacOS extensions, and enables nocrash during
'configure'.
* make-dist: Adjust to new build-aux and build-aux/snippit dirs.
* admin/notes/copyright: The files compile, config.guess, config.sub,
depcomp, install-sh, missing, and move-if-change are now in the
new build-aux subdirectory. The files arg-nonnull.h, c++defs.h,
and warn-on-use.h are now in build-aux/snippets. New file
build-aux/snippets/_Noreturn.h.
* leim/Makefile.in (install): install-sh is now in build-aux.
* lib-src/Makefile.in ($(DESTDIR)${archlibdir}): install-sh moved
to build-aux.
* msdos/sedlibmk.inp (CONFIG_CLEAN_VPATH_FILES): Adjust to snippet moves
from top level to build-aux/snippet.
* src/Makefile.in (gl-stamp): move-if-change is now in build-aux.
test, which runs afoul of Automake installations where, for example,
/usr/share/aclocal contains a copy of gl_THREADLIB.
Problem reported by Sven Joachim in
<http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00529.html>.
This is just a quick temporary fix, specific to Emacs; I'll work
with the other gnulib maintainers to get a more-permanent fix.
* Makefile.in (GNULIB_TOOL_FLAGS): Do not avoid sigprocmask.
* configure.in (AC_TYPE_UID_T): New dummy macro.
Configure gnulib after adjusting LIBS,
so that gnulib can assume the libraries in LIBS.
* lib/pthread_sigmask.c, lib/sigprocmask.c, m4/signalblocking.m4:
New files, automatically imported from gnulib.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
* src/Makefile.in (LIB_PTHREAD_SIGMASK): New macro.
(LIBES): Use it.
* Makefile.in (GNULIB_MODULES): Add pthread_sigmask.
(GNULIB_TOOL_FLAGS): Avoid sigprocmask. Emacs does its own
implementation of 'sigprocmask' on Windows, and it assumes
'sigprocmask' on non-Windows hosts, so it doesn't need the
sigprocmask module.
* lib/signal.in.h, m4/pthread_sigmask.m4, m4/signal_h.m4:
New files, automatically imported from gnulib.
* lib/gnulib.mk, m4/gl-comp.m4: Automatically-imported update
due to the above changes.
* .bzrignore: Add lib/signal.h.
* Makefile.in (GNULIB_MODULES): Add dup2.
* configure.in: Do not check for dup2; gnulib does that now.
* lib/dup2.c, m4/dup2.m4: New files, from gnulib.
* src/sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
* .bzrignore: Add lib/alloca.h.
* Makefile.in (GNULIB_MODULES): Add alloca-opt.
* configure.in (AC_FUNC_ALLOCA): Remove almost all the alloca stuff,
as gnulib now does that for us. Put alloca check after gl_INIT.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
* lib/alloca.in.h, m4/alloca.m4: New files, from gnulib.
fakemail: Remove dependency on ignore-value.
* Makefile.in (GNULIB_MODULES): Add stdio.
* lib/stdio.in.h, m4/stdio_h.m4: New files, automatically
imported from gnulib.
[lib-src/ChangeLog]
fakemail: Remove dependency on ignore-value.
This undoes some of the recent fakemail-related changes.
It is made possible due to recent changes to gnulib's stdio module.
* Makefile.in (fakemail${EXEEXT}): Do not depend on ignore-value.h.
* fakemail.c: Do not include ignore-value.h.
(put_line): Do not use ignore_value.
Work around some portability problems with symlinks.
* Makefile.in (GNULIB_MODULES): Add lstat, readlink, symlink.
* configure.in (lstat, HAVE_LSTAT): Remove special hack.
* lib/lstat.c, lib/readlink.c, lib/stat.c, lib/symlink.c:
* m4/dos.m4, m4/lstat.m4, m4/readlink.m4, m4/stat.m4, m4/symlink.m4:
New files, automatically generated from gnulib.
* aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk:
* lib/stdlib.in.h, m4/gl-comp.m4, m4/stdlib_h.m4: Regenerate.
2011-02-22 Paul Eggert <eggert@cs.ucla.edu>
[src/ChangeLog]
Work around some portability problems with symlinks.
* fileio.c (Frename_file, Fmake_symbolic_link, Ffile_symlink_p):
Simplify the code by assuming that the readlink and symlink calls
exist, even if they always fail on this host.
(Ffile_readable_p): Likewise, for fifos.
* config.in: Regenerate.
