Hi Segher!

Your patch fixes the issue for me. I had issues building ghc on powerpcspe.
With gcc-6 it failed in the expected way, with gcc-7, it went past the
problematic source code file.

Would it be possible that your backport your fix to the gcc-6 branch so we can
use it in the current Debian release?

Thanks,
Adrian
