--- Comment #7 from Iain Sandoe <iains at gcc dot gnu.org> 2011-10-27 10:54:50 UTC --- I applied the patch at http://gcc.gnu.org/ml/gcc-patches/2011-10/msg02441.html (no difference to the problem at hand). The only definite thing I've spotted so far is in the args file: -B\ /Volumes/ScratchCS/gcc-4-7-trunk-build/gcc/ if I try to do ./gcc/xgcc @<path/to/args/file with this in it; xgcc doesn't find lto1. If I replace the escaped space with either a space or a new line it works.
