This incorporates the following changes:
2013-09-19 stdio: OS X port of putc_unlocked + extern inline
2013-09-19 signal: OS X port of sigaddset etc. + extern inline
2013-09-19 extern-inline: do not always suppress extern inline on OS X
2013-09-17 getgroups: statement without effect
2013-08-28 headers: check that _GL_INLINE_HEADER_BEGIN is defined
* 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.
* 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.
