Microsoft predefines _WIN32 for Windows 64, too!
D:
    Windows: All members of the Windows family
    Win32: specific to Windows 32
    Win64: specific to Windows 64
That seems sensible to me.

The __ are ugly but necessary because of the C standard, but they are 
ugly and *unnecessary* for D.

Apple has made many operating systems besides OSX, so __APPLE__ is out. 
I can't even remember which OS Mach is.

Because the gcc macro suits the need perfectly. The others don't.

If gcc had any consistency, I'd use that. But it doesn't. It makes sense 
to use gcc's precedent when gcc makes sense, and to diverge when gcc 
does not make sense.
