* configure.ac (TEMACS_LDFLAGS2): Don't define.
(LIBS_GNUSTEP): Set for GNUstep and substitute.
(LD_SWITCH_SYSTEM_TEMACS): Don't set for GNUstep.
* src/Makefile.in (TEMACS_LDFLAGS2): Remove.
(LIBS_GNUSTEP): Define.
(LIBES): Add $(LIBS_GNUSTEP).
(temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
* Makefile.in (uninstall): Don't abort if some directories are missing.
Apply transformation rules to manual pages, desktop and icon files.
No more emacs22 icons to uninstall.
Some people prefer them to the newer icon
* Makefile.in (install-etc): Don't install emacs22 icons.
* etc/images/icons/hicolor/32x32/apps/emacs22.png:
* etc/images/icons/hicolor/16x16/apps/emacs22.png:
* etc/images/icons/hicolor/48x48/apps/emacs22.png:
* etc/images/icons/hicolor/24x24/apps/emacs22.png: Restore old icons.
* etc/images/icons/README: Restore info about emacs22 icons
* .bzrignore: Add lib/fcntl.h.
* configure.ac (euidaccess): Remove check; gnulib does this for us now.
(gl_FCNTL_O_FLAGS): Define a dummy version.
* lib/at-func.c, lib/euidaccess.c, lib/faccessat.c, lib/fcntl.in.h:
* lib/getgroups.c, lib/group-member.c, lib/root-uid.h:
* lib/xalloc-oversized.h, m4/euidaccess.m4, m4/faccessat.m4:
* m4/fcntl_h.m4, m4/getgroups.m4, m4/group-member.m4:
New files, from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* admin/merge-gnulib (GNULIB_MODULES): Add faccessat.
(GNULIB_TOOL_FLAGS): Avoid at-internal, fchdir, malloc-posix,
openat-die, openat-h, save-cwd. Do not avoid fcntl-h.
Omit gnulib's m4/fcntl-o.m4.
* nt/inc/ms-w32.h (AT_FDCWD, AT_EACCESS): New symbols.
(access): Remove.
(faccessat): New macro.
* src/Makefile.in (LIB_EACCESS): New macro.
(LIBES): Use it.
* src/callproc.c (init_callproc):
* src/charset.c (init_charset):
* src/fileio.c (check_existing, check_executable):
* src/lread.c (openp, load_path_check):
* src/process.c (allocate_pty):
* src/xrdb.c (file_p):
Use faccessat, not access or euidaccess. Use symbolic names
instead of integers for the flags, as they're portable now.
* src/charset.c, src/xrdb.c: Include <fcntl.h>, for the new flags used.
* src/fileio.c (Ffile_readable_p):
Use faccessat, not stat + open + close.
(file_directory_p): New function, which uses 'stat' on most places
but 'access' (for efficiency) if WINDOWSNT.
* src/fileio.c (Ffile_directory_p, Fset_file_times):
* src/xrdb.c (file_p): Use file_directory_p.
* src/lisp.h (file_directory_p): New decl.
* src/lread.c (openp): When opening a file, use fstat rather than
stat, as that avoids a permissions race. When not opening a file,
use file_directory_p rather than stat.
* src/process.c, src/sysdep.c, src/term.c: All uses of '#ifdef O_NONBLOCK'
changed to '#if O_NONBLOCK', to accommodate gnulib O_* tyle.
* src/w32.c (sys_faccessat): Rename from sys_access and switch to
faccessat's API. All uses changed.
Fixes: debbugs:12632
* configure.ac (sys_siglist): Look for its decl in <signal.h>.
Otherwise, it's not found in either Fedora 17 or Solaris 11.
* src/sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
defined as a macro, as is done in Solaris.
(sys_siglist_entries): New macro.
(save_strsignal): Use it.
* src/syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
OpenBSD problem reported by Han Boetes.
* profiler.c (setup_cpu_timer): Check for failure of timer_settime
and/or setitimer.
(Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
* syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
like OpenBSD, which has timer_settime but does not declare it.
OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
whether to use itimerspec-related primitives. All uses of
HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
This should fix an OS X build problem reported by Ivan Andrus in
<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00671.html>.
* admin/merge-gnulib (GNULIB_MODULES): Add timer-time.
* configure.ac (gl_THREADLIB): Define to empty, since Emacs
does threads its own way.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* m4/timer_time.m4: New file, from gnulib.
* src/atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
call timer_settime.
to create 'configure'; problem reported by Andreas Schwab in
<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00438.html>.
* autogen.sh: Exit with status 1 when failing due to missing tools,
reverting the 2012-09-10 change to this file.
* autogen/copy_autogen: Fail if one of the subsidiary actions fail.
Use 'cp -f' for the build-aux files, since the destinations are
typically read-only.
($(MAKEFILE_NAME)): Pass MAKE='$(MAKE)' to config.status's env.
Suggested by Wolfgang Jenker in
<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00430.html>.
(MAKE_CONFIG_STATUS): Remove. Remaining use expanded.
This undoes part of the 2012-09-10 patch.
(bootstrap): Run ./configure, rather than trying to run config.status
if it exists. That builds src/epaths.h more reliably.
The workaround was for improving performance on Solaris 2.4, but
is getting in the way now. Emacs will still work if someone is
still running Solaris 2.4 in a museum somewhere; Sun dropped
support for Solaris 2.4 in 2003.
* configure.ac (ac_cv_func_vfork_works): Default to 'no' on
Solaris 2.4, so that AC_FUNC_VFORK doesn't think vfork works.
* src/callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
* src/process.c (create_process) [HAVE_WORKING_VFORK]:
Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
since Emacs no longer uses vfork on that platform.
