Ideally it should be USE(THE_SPECIFIC_FRAMEWORK_IN_QUESTION). I would guess 
that much of PLATFORM(MAC) that is valid for both Mac and iOS should actually 
be USE(FOUNDATION). PLATFORM really shouldn't be used for things other than 
terminal platform names. USE(COCOA) would be an ok stopgap if sorting down to 
more specific conditionals delays this cleanup too much.
