First this whole "gcc -unknown" is PR 15303.

Second I still think it is hard to get this correct as on darwin with
some versions (really Apple's) of GCC accepted -no-cpp-precomp but newer
ones (from both the FSF and Apple) don't accept it (though we what we
will need a spec for warning about an option which has been removed and
then PR 15303 can be resolved because resolving it currently will
cause a bootstrap failure with starting with that version of GCC).


Thanks,
Andrew Pinski
