IMO only project developers should ever be touching the autotools. Source code tarballs should have a correctly
generated configure script included, and of course those scripts list the version number of the autoconf script
that generated them. This is how it works in OpenLDAP, anyway. Only our release engineer ever generates the
configure script, and it's committed to the repo along with everything else.
