Yup. We aren't changing back autoconf versions if we can help it ---
too much risk of breakage.

It's not a big problem if you install 'em into private subdirectories,
eg I have autoconf-2.53 installed with --prefix = /usr/local/autoconf-2.53
and doPATH=/usr/local/autoconf-2.53/bin:$PATH autoconf
when I need to update back-branch configure scripts.
