+ Merge from gnulib, using build-aux to remove clutter (Bug#9169).
+ * autogen/README: Update destination list.
+ * autogen/copy_autogen, autogen/update_autogen, .bzrignore:
+ The autogenerated files compile, config.guess,
+ config.sub, depcomp, install-sh, and missing are now in build-aux.
+ * 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.
+ * 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.
