configure: Don't special case Cygwin to use gnu99, define _XOPEN_SOURCE instead

Browse source 
Revert "build: Build on Cygwin with gnu99 instead of c99." and define
_XOPEN_SOURCE appropriately.

This reverts commit 53e36d333c.

Since Cygwin 1.7.18 (April 2013), it's headers correctly prototype strtoll()
when using -std=c99, and correctly prototype strdup() when _XOPEN_SOURCE is
defined appropriately, so this workaround is no longer needed.
