Khtml is much more different than GCC. Surely khtml needs a lot of libraries 
so you can't compile it by himself, but if you compile all of KDE on ANY of 
the those uncompatible mentioned unixes you will get the khtml compiled and 
running on it!
Being the core part of development, GCC seems to be different.  could not find 
anything on the apple's  site about the Mac's GCC; what I saw was just the 
release note of it. 
Anyway if Mac's CC using something special to Mac OS kernel I can say that 
they messed it up - remember that you can compile the original GCC on Mac - 
if not it can compile on linux. 
Anyway I am not going to try compiling this on linux; but would be glad if you 
can give me the url of source. 

This way you will talk about  GNU/Mac in the future!
