--- Comment #11 from Kai Tietz <ktietz at gcc dot gnu.org> --- this doesn't seem to be related with my patch at all. It looks more like you are trying to re-use an old build tree. Patch is made against trunk. Nevertheless should work for 6.x branch, too. I build in general just a cross-compiler, and this works with and without this patch flawless.
