Subject: 	* barrier.c: Move _LONG and _LPLONG defines into 
 implement.h; rename to PTW32_INTERLOCKED_LONG and 
 PTW32_INTERLOCKED_LPLONG respectively. 	* spin.c: Likewise;
 ptw32_interlocked_compare_exchange used 	in place of
 InterlockedCompareExchange directly. 	* global.c
 (ptw32_interlocked_compare_exchange): Add 	prototype for this new routine
 pointer to be used when 	InterlockedCompareExchange isn't supported by
 Windows. 	* nonportable.c (pthread_win32_process_attach_np): Check for 
 support of InterlockedCompareExchange in kernel32 and assign its 
 address to ptw32_interlocked_compare_exchange if it exists, or 	our
 own ix86 specific implementation ptw32_InterlockedCompareExchange. 
 *private.c (ptw32_InterlockedCompareExchange): An 	implementation of
 InterlockedCompareExchange() which is 	specific to ix86; written directly in
 assembler for either 	MSVC or GNU C; needed because Windows 95 doesn't
 support 	InterlockedCompareExchange().

	* sched.c (sched_get_priority_min): Extend to return
	THREAD_PRIORITY_IDLE.
	(sched_get_priority_max): Extend to return
	THREAD_PRIORITY_CRITICAL.
