OK.. done.. Made one minor fix to the implementations for an extra
argument to decrement count (checked into CVS). The results for the
timing test are:


* cw-8.3 debug, 18.06
* gcc-3.3 debug, 50.98
* gcc-3.3 release, 18.47


* cw-8.3 debug, 21.08
* gcc-3.3 debug, 51.07
* gcc-3.3 release, 18.52

I didn't build the release of cw-8.3 because it was taking along time,
more than 10 minutes, to compile some of the files. It's most likely one
of the unbounded optimizations CW likes getting into.

To me the curious aspect is that CW is faster in debug mode than GCC in
release mode. It's nice to see the threaded code be almost as fast as
the non-threaded code.

Oh, I guess I only implied that all tests did pass. And I didn't mention
that my machine is only a G3-233.
