So if I define the _WIN64 macro for AXP all of the *_PTR should be ok right? I will submit a patch
for this in short order.

I have this Alpha that HP loaned us for ReactOS but I have never been able to build a current
gcc/binutils that build for a alpha-pe target. I figure while I still have it then I will work on
getting WINE working. Anyone know AXP assembly interested in helping with the port? I will put it
on the net with SSH if anyone wants to play with it.
