+platform dependence
+-------------------
+As Win9x doesn't provide one, the library now contains
+it's own InterlockedCompareExchange() routine. It is used to
+implement spinlocks and barriers, and soon may be used in mutexes.
+This routine relies on the CMPXCHG machine instruction which
+is only available in i486 or above CPUs. This library
+(from snapshot 20010712 onwards) therefore no longer runs on
+i386 platforms.

Restored pthread_rwlock_wrlock() as a cancelation point as permitted
-by POSIX 1003.1j. (Was prematurely disabled in the the last snapshot.)
