There's a problem with this: Autoconf 2.61 was only released in
November this year, and it requires a new version of M4 (1.4.8), which
in turn requires a new libc6.  Most existing GNU/Linux distributions
won't have these packages (at least in their "stable" branches).

I could try to install these packages, but it would be a major hassle
because the libc6 requirement would effectively require an entire-OS
upgrade.  (This would be a hassle for any other developer who may want
to regenerate configure).

I don't think this bug is serious enough to warrant switching autoconf
versions, especially since we don't know what new bugs the new
autoconf version might introduce.  I suggest simply documenting this
in PROBLEMS and recommending the new version of autoconf there.
