--- Comment #2 from Nathaniel Shead <nshead at gcc dot gnu.org> --- Sorry about that. I've not been able to work out what configure flags I need to pass to cause this to error in the first place (I don't normally develop for powerpc and the machine I'm using doesn't seem to fail no matter what flags I try), but am I correct in understanding that just adding "-Wno-psabi" to the tests should stop them from failing? If so I'm happy to push a patch to that effect.
