--- Comment #1 from dodji at seketeli dot org <dodji at seketeli dot org> 2012-05-24 18:43:52 UTC --- Right, and there is: #elif (GCC_VERSION >= 4005) && defined(__ALTIVEC__) right before the offending line, which explains why I haven't seen the bootstrap error before committing, as I don't run any ALTIVEC system. I'll cook up a patch for this. Thank you for filling this bug.
