           Summary: stage 2 powerpc-darwin8 compile error without proper

After a successfully built (with g++-4.0.1) powerpc-darwin8 llvm and clang
(r167855), and showing that hello-world compiled and ran successfully, I
embarked on stage 2 of self-hosting/bootstrap.
A few translation units in, I get compile failures with no diagnostic except
10000s of lines of assembler errors:

I don't know what is actually wrong, but certainly there needs to be some
meaningful diagnostic message.
Will post more details as find out more...
