How about making it so autoconf is required, only if you modify
configure.in or otherwise fiddle with mtimes to make it look like
configure is out of date?

Why cater to developers who lack the required version of autoconf?
Anyone clueful enough to build from source also knows enough to install
autoconf if they don't have it already.  As long as the requirement is
documented, no one can complain.  Heck, I'll even provide a script to
download/check-sig/build/install autoconf into a private directory.
I did that for another project (qpid) that also required automake
and libtool.
