Can you sent me the full output? I don't have the time to compile gcc from scratch right now and none of the usual suspects supports ObjC - that alone is a sign that no one really uses gcc on OS X (other than for ports) since Apple has abandoned it. My guess would be that the ObjC support is not as complete as in Apple's version - it's probably more geared toward GNUstep - but that's just a guess.

Cheers,
Simon
