mv tmp-libgcc.mvars libgcc.mvars
/bin/sh ../../trunk.git/gcc/../move-if-change tmp-fixinc_list fixinc_list

It could be clang/llvm miscompiling stage 2. Can you try with gcc as the
original compiler?

Thanks for the suggestion. I did that, and the problem seems to have gone away
;->
7.5 hours of compilation and not yet finished, though.

I think if the problem has gone away, then it looks like clang is miscompiling.
Not a problem in gcc, then. I think this bug can be closed.
