autoconf 2.69 upgrade was only partially completed.

So far we have autoconf (6b81910fc) and autoheader (c2f75cd10). However running
autoreconf 2.69 still generates more diffs.

At least aclocal still needs to be run. This ITS is a reminder to check what
else autoreconf does and check in the remaining changes.

In future it might be good practice to get in the habit of running autoreconf
instead of just autoconf. It tries and fails to run Automake, but that can
probably be addressed (possibly by deleting the AM_INIT_AUTOMAKE call).
