Well, I've been using autoconf since...since we moved everything over to
it, what, two years ago?  I have yet to see a problem using one version
over the next.  If you can show a problem, please feel free to point it
out, but until we can do that, requiring 2.12 or 2.13 explicitly, IMHO, is
ridiculous.  flex 2.54+ made sense, because of an acknowledged
problem...autoconf versions, though, there are no acknowledged problems
between each that I'm aware of...
