[darwinbuild] Re: Darwin 8.0.1 gcc for pentiumpro

[Shantonu Sen]

Woah, dude, that's not how you run gcc. gcc invokes language-specific  
backends, for example /usr/libexec/gcc/darwin/ppc/3.3/cc1.

It sounds like you used a Kevin's gcc driver but not the language  
backend. Don't do that. You need to chroot into the build root to use  
it properly.
