IIRC, in the past we've encountered Autoconf bugs going both ways
(i.e. in versions that are new and versions that are old).  When we
begin pretesting Emacs 24, we will want to pick one Autoconf version and
stick to it, unless/until a specific problem is found with that version.

But at the moment the choice of Autoconf version probably doesn't
matter.
