I wonder if it would be better to make the default 2.7 in order to more strongly 
encourage maintainers to try the latter.  They can always set WANT_AUTOCONF=2.5 
if they can't make it work.  But I would bet that most difficulties that arise 
have already been found and fixed by Fedora.

Does Fedora build Windows exes?
Do most packages use libtool?
Remember gnulib? ;^>
