No, you shouldn't use these macros. They are Windows-specific and correspond 
to InterlockedIncrement/InterlockedDecrement but don't require the inclusion 
of windows.h. If you are targeting the new C++0x, use std::atomic; 
otherwise, until Boost.Atomic is available, you may try 
boost::detail::atomic_count. It's, however, undocumented.
