[Mesa-dev] [PATCH 1/4] configure: Define _GNU_SOURCE for Cygwin as well

[Jon Turney]

From: Yaakov Selkowitz <yselkowi at redhat.com>

Cygwin headers are now a bit more correct in handling feature test macros,
so use _GNU_SOURCE when building for Cygwin, as well.

(Notwithstanding f381c27c, we should probably have always been using
_GNU_SOURCE, since asprintf() is used by mesa in places)
