For that specific question we have COMPILER(X). But I think I  
understand what you're getting at.

It seems to me that we have two conflicting kinds of uses of PLATFORM.

Use 1: Defining whether to use large platform libraries, e.g,  
PLATFORM(CG), PLATFORM(CF), PLATFORM(CURL)
Use 2: Defining a whole "port" or "flavor" of WebKit, e.g.,  
PLATFORM(MAC), PLATFORM(WIN)

It might be beneficial to have separate macros for Use 1 and Use 2.
