For application to HEAD, following community review.
* Changes incorrect CYGWIN defines to __CYGWIN__ * Some localtime returns NULL checks (when unchecked cause SEGVs under Win32 regression tests) * Rationalized CreateSharedMemoryAndSemaphores and AttachSharedMemoryAndSemaphores (Bruce, I finally remembered to do it); requires attention.
