I must have missed checking this before using
InterlockedCompareExchange in the barrier and spinlock routines
that were added at snapshot 2001-07-12. I run the testsuite
on a Win98 machine before releasing snapshots.

Snapshot 2001-07-03 should be OK to use. Apart from not having
spinlocks and barriers, there are only a few minor bug fixes
that are the difference.

I'll have to fix this for the next snapshot so that Win95 and
pre-NT4.0 is properly supported again.

Thanks for pointing out the error.
