On Xcode 3.1.2 (with iPhone DevKit, though I highly doubt that matters), I
see:
GCC 3.3, GCC 4.0, GCC 4.2, GCC System Version (4.0), LLVM-GCC 4.2.

I not installed any GCCs from MacPorts, and I'm not quite sure what the
difference is between GCC 4.0 and GCC System Version (4.0)...  (I actually
hadn't noticed that until now...)

Do you think we need to change the naming conventions for that though?
