--- Comment #10 from Iain Sandoe <iains at gcc dot gnu.org> --- sorry I fixed this months ago locally.. I will push a patch to fix ASAP. note that there are 4 bootstrap breakers on PPC (trunk) 1. this 2. libcc1 (same fail as x86) 3. libiberty needs some options massage to build PIC properly (will also break i686-darwin*) 4. libada is currently looking for __environ and needs a modification to the makefile, affects at least 10.5, 10.6
