	(ivmai138.diff)

	* Makefile.direct (DONT_USE_SIGNALANDWAIT): Add the comment for.
	* win32_threads.c (DONT_USE_SIGNALANDWAIT): Always define for
	WinCE.
	* win32_threads.c (THREAD_HANDLE): Cast Id (of DWORD type) to
	HANDLE thru word type (to avoid a compiler warning) for WinCE.
	* win32_threads.c (GC_marker_cv, GC_marker_Id): New static array
	(only if DONT_USE_SIGNALANDWAIT).
	* win32_threads.c (start_mark_threads): Initialize GC_marker_Id
	and GC_marker_cv for each helper thread (only if
	DONT_USE_SIGNALANDWAIT).
	* win32_threads.c (GC_mark_mutex_state): New static variable (only
	if DONT_USE_SIGNALANDWAIT).
	* win32_threads.c (GC_mark_mutex_waitcnt,
	signalObjectAndWait_func): Don't define if DONT_USE_SIGNALANDWAIT.
	* win32_threads.c (GC_acquire_mark_lock, GC_release_mark_lock):
	Use InterlockedExchange() over GC_mark_mutex_state (instead of
	AO_fetch_and_add()) if DONT_USE_SIGNALANDWAIT.
	* win32_threads.c (GC_wait_marker, GC_notify_all_marker):
	Implement wait/broadcast primitives using Win32 multiple events
	(one for each marker thread) if DONT_USE_SIGNALANDWAIT (instead of
	using Win32 SignalObjectAndWait).
	* win32_threads.c (GC_thr_init): Don't declare hK32 local
	variable, don't check for GC_wnt, and don't initialize
	signalObjectAndWait_func if DONT_USE_SIGNALANDWAIT.
