Log message:
	* include/winnt.h (MemoryBarrier): Define to __mingworg_MemoryBarrier()
	which is in libmingwex.a.
	MODIFIED FROM: Use __sync_synchronize instead of
	creating a function due to multiple definition.
	NOTE: Not using __sync_synchronize to allow applications to mix-n-match
	C libraries from different vendors.
