+       gnulib, autoconf: update.
+       * README-hacking (Updating a submodule): Give advice on how to
+       determine the versions of gnulib and autoconf to which we should
+       update.
+       (Release Procedure): Note that submodules should be updated.
+       * bootstrap.conf (gnulib_modules): Rename pipe to spawn-pipe as
+       suggested in updated gnulib NEWS.
+       * gnulib: Choose a stable snapshot according to advice in Bison's
+       README-hacking.
+       * po/POTFILES.in (lib/pipe.c): Rename to...
+       (lib/spawn-pipe.c): ... this.
+       * src/output.c: Update to include spawn-pipe.h.
+       * submodules/autoconf: Update to latest for improvement in m4.m4
+       that excludes M4 with buggy strstr.  The only other changes to
+       files that we use are copyright updates.
