of the basic ObjC changes will be in gcc/objc; there are a couple

will need extra special attention.

This seems to me like a sensible plan.

Is there any hope of ObjC runtime unification, and of documenting the

I think that would be ambitious for 3.4. Our main goal for 3.4 is to contribute Apple's changes to the general community. I think that's doable, but much more than that probably isn't.

I should mention, by the way, as someone who doesn't deal much with
ObjC++ other than in its impact to cc1plus: ObjC++ does involve a few
changes to the C++ front end, but they're very harmless changes.  (A
few functions renamed---that sort of thing.)  I don't think anyone is
going to mind the changes we need for ObjC++.
