I know this message is ancient, but if you are still

seems to be kind of a proving ground for the C++ working group. Lots of
libraries which are cross platform and written by smart people. See
www.boost.org.
Hope this helps... mo

Thanks for the pointer, mo.
Where are these primitives actually defined? I found this in
once.cpp...
// The friendly form of InterlockedCompareExchange that defers
// according to the above function type wrappers.
inline LONG compare_exchange(volatile LPLONG dest, LONG exch, LONG cmp)
{
return ice_wrapper(&InterlockedCompareExchange, dest, exch, cmp);
}
But, I can't figure out where the ice_wrapper stuff is defined. I
suspect it may be the interesting part, some kind of machine-dependent
layer.
