--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> --- OK, then ALT128_COMPAT is effectively only for LE. So I think I'll make whatever change is needed so that ALT128_COMPAT isn't defined for power6 LE and power7 LE, so the errors Matthias found don't happen. But I won't spend time trying to actually make it work well on the unsupported power6 LE combo.
