Yes, I was specifically looking for a define to tell us we are on windows, 
rather than one telling us we are using MSYS.
That's mostly because David and others have recently suggested the possibility 
of building ObjC code using the microsoft compiler.

I think most of the windows-specific code we have is not really msys/mingw 
specific, so we should propbably be reserving the use of __MINGW... for places 
where it makes a difference.
