It's been a while since I've devoted any time to the m4 master branch, as
evidenced by this submodule jump of 635 commits in gnulib. One of the
biggest problems was figuring out how to use gnulib-gnu instead of the
deprecated gnulib module; and in the meantime, gen_tempname changed
signatures (twice) and the gnulib testsuite started pulling in rpl_setenv,
which caused a link error on cygwin 1.5 if modules/stdlib didn't also use
it. There's still an outstanding bug report that the testsuite is too
strict on parsing expected output from getopt failures, which is only made
worse by the fact that getopt no longer needs replacement on modern BSDs,
even though they spell error messages differently. I'll work on that next.

Don't work too hard, make some time for fun as well!

>From 7873c5c3cd64575aec4b69de326aa683309d4ba4 Mon Sep 17 00:00:00 2001
From: Eric Blake <e...@byu.net>
Date: Thu, 26 Nov 2009 12:58:05 -0700
Subject: [PATCH] Update to newer gnulib.
* gnulib: Update.
* ltdl/m4/gnulib-cache.m4: Import inttypes, setenv, and unsetenv
modules.
* modules/m4.c (m4_make_temp): Adjust gen_tempname client.
* bootstrap (src_modules): Pick up getopt-gnu and its
dependencies.
* configure.ac (gl_VERSION_ETC): Support ./configure
--with-packager.
(AC_CHECK_FUNCS_ONCE): Rely on gnulib for setenv, unsetenv.
* ltdl/m4/m4-getopt.m4: Rewrite to match current gnulib.
* Makefile.am (src/getopt.h): Likewise.
* modules/stdlib.c (setenv, unsetenv): Rely on gnulib.
