Actually MS decision is vastly more sensible than the gnu choice:
it leaves all the ints the same size on win32 and win64,
so all strictly conforming code will continue to work the same 
way, right up to integer overflow, bit masks, etc.

The real 'gotcha' is the Unix programmers that decided
it was OK to use 32 bit ints as addresses .. their code
will break under both models.
