The autogen.sh script at heart only calls a couple of other auto* programs,
and doesn't change much between releases. The complexity is only that it
is checking versions of the auto* tools because autoconf has no compatibility
between releases.
You can get any old version, and I've attached one here for posterity:

ch_cur=`echo $1 | sed 's/[^0-9].*$//'`; shift # remove letter suffixes
