The thing is, it *isn't* the Autoconf Way: test for features, not versions. There is one good use case for “use v5.xx” in a Perl program: when you’re requiring a particular version of the Perl interpreter, to use language features that didn’t exist and couldn’t be patched in with packages before that. This is not that case. However, I will repeat a point from an earlier thread: the generated configure scripts from the new version of Autoconf will continue running on these older systems. The only thing being broken is the ability to *generate* configure scripts with Autoconf on those ancient systems.
