* Merge from gnulib, using build-aux to remove clutter.Paul Eggert2011-07-241-10/+230
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
* * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK): Omit gl_THREADLIBPaul Eggert2011-07-091-51/+1
| | | | | | | | | 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.
* Simplify Emacs part of pthread_sigmask support.Paul Eggert2011-07-081-13/+64
| | | | | | | | | | | | * 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.
* Add gnulib support for pthread_sigmask.Paul Eggert2011-07-061-0/+26
* 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.
