Maybe. I was trying to avoid sp_counted_base_* variations unless necessary. 
Since we need g++/x86 for non-Windows platforms anyway, it seems reasonable 
to use it on Windows, too.

I wonder if CodeWarrior supports the _Interlocked* family as intrinsic 
functions. If it does, we'll just need to enable the appropriate path in 
detail/interlocked.hpp for __MWERKS__.

In any event, I think that this can wait for after 1.33 is released.
