Hello,
Please review this small patch to configure which enables building on
Cygwin 2.0 and newer. Instead of explicitly testing for all versions we
know work, I inverted the check to exclude the ones we know won't work.
Hitting a known bad Cygwin version should be very rare anyway since 1.7
has been around for a long time now and Cygwin is so aggresive with
keeping people updated.
