Well, front-ends are probably my weakest area in the compiler itself, and it
only gets worse for languages like C++ which I don't know or understand :-)

From a high level I'd have the same concerns that other folks have expressed.
Primarily that we don't want to duplicate a lot of code.  The other concern
is we don't want to bludgeon the C++ front end too much and make life too
difficult on the folks working on our C++ compiler.

In the end, Jason and the other folks working on the C++ front end will have
to decide which side of the fence to fall on.

Note that you'll need to deal with the copyright assignment issues before any
of this work can be integrated.

I'd look in objc/Makefile.in and objc/Make-lang.in

gcc.c?  Maybe?  I'm not good with the spec stuff either (can you tell my
background is optimizers and backends :-)
