Fix 'failed to create new win32 semaphore' Cygwin fatal error at fork
Issue #522 (bdwgc).
The solution is to use semaphore operations emulation provided
in darwin_semaphore.h.
* include/private/darwin_semaphore.h [!GC_DARWIN_THREADS]: Preprocessor
error only if not GC_WIN32_THREADS; update error message.
* include/private/darwin_semaphore.h: Update comment.
* include/private/gcconfig.h [CYGWIN32 && GC_WIN32_THREADS
&& CAN_HANDLE_FORK && !EMULATE_PTHREAD_SEMAPHORE
&& !CYGWIN_SEM_FIXUP_AFTER_FORK_BUG_FIXED] (EMULATE_PTHREAD_SEMAPHORE):
* pthread_support.c [GC_PTHREADS && GC_WIN32_THREADS
&& EMULATE_PTHREAD_SEMAPHORE]: Include darwin_semaphore.h instead of
semaphore.h.
