Autoconf upstream has stated that the 2.7x releases are not fully
backwards compatible. Cygwin therefore chose to provide a new
autoconf2.7 package (keeping autoconf2.5 available) and modifying the
wrapper script to allow packaging systems to set WANT_AUTOCONF=2.7 to
select a newer autoconf version. The default (when no explicit
WANT_AUTOCONF is set) is still "2.5", which selects autoconf version
2.69 on Cygwin.
As you explained on IRC earlier today, what you meant is that the default for
packages built via cygport is still 2.5.
The default will change to "2.7" after some period of
testing.
Cygwin package maintainers are encouraged to set WANT_AUTOCONF=2.7 in
their cygport configuration or in individual cygport files in order to
check for regressions.
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.
