I think we'd be setting ourselves up for a user support nightmare, as
others have mentioned. But just to see what the state of the art is...

The gcc-3.4.1 suite has a confiugre flag --enable-altivec:
Specify that the target supports AltiVec vector enhancements. This
option will adjust the ABI for AltiVec enhancements, as well as
generate AltiVec code when appropriate. This option is only
available for PowerPC systems.
It sounds like Apple is contributing ObjC++ support back upstream:
http://gcc.gnu.org/ml/gcc/2004-06/msg00818.html
but I don't know if it's done yet. But even if it's there by 3.5 (or
some branch thereof, or whatever we can find to release), it feels like
we'd always be _at_best_ up to the same version# as Apple's. Though
there are arguments to be made for having a known-to-be-functional
thing as a fallback for when Apple hoses us.
