I thought gcc built its own bootstrap compiler to do the heavy lifting of the build. Can LLVM not build the bootstrap compiler or was I mistaken in thinking this?

The bootstrap process for gcc involves first building gcc with an existing C compiler, then rebuilding gcc from this first build [1].

I'm still waiting for my build to finish, but i686-apple-darwin11-llvm-gcc-4.2 seems to be handling the gcc 4.7 source fine.

Ah for some reason I had in my head the bootstrap was a smaller, simpler compiler. Thanks for the link and clarification.
