I suppose that depends what "Unix" means to you.  Windows also has a 
Posix subsystem, Interix, which should definately classify as Unix.  So 
you could theoretically have Windows, Win32, Unix, and Interix all 
defined for a Windows platform.  Personally, I find Posix to be more 
meaningful here, but it's splitting hairs.
