Yes.  That was addressed in r80732.  I'm content just not bothering with llvm-gcc if clang works as a replacement.

<snip gmp />

CCing mww so he sees these gcc items vvvv   ... this really should've been in a ticket...

I'd use darwin[1-9][1-9]* consistently rather than darwin[12]* places and darwin[1][1-9]* places
