Cygwin POSIX semaphores patch

[Jason Tishler]

[Please CC me on replies since I am not subscribed to this list.]

Since Cygwin supports POSIX semaphores, features.h should indicated this
fact.  The attached patch has been discussed on cygwin-developers and
cygwin-patches and the Cygwin community agrees with it.

If interested, see the following for details:
