What a coincidence, I had posted a patch this very days about this issue:
<http://lists.gnu.org/archive/html/bug-autoconf/2013-01/msg00001.html>

That patch has already been pushed, so that the fix will appear in the
next Autoconf version (2.70).

Autoconf uses Git, not SVN; for details about how to clone the git
repository, refer to <http://savannah.gnu.org/git/?group=autoconf>
