I updated /usr/src and amd64 to -r319991 and then retried cross building for powerpc: same result. Note: I'd frozen at -r317820 until this update. Back then I could buildworld and buildkernel via clang (although I could not boot the clang-based kernel and so had to build a gcc 4.2.1 based one and use it). =3D=3D=3D Mark Millard markmi at dsl-only.net
