The same failures are also seen under x86_64-apple-darwin12 when using the llvm.org's 3.2 release branch clang compilers to bootstrap gcc trunk (so it isn't limited to Apple's clang compilers). > > > > > > > > My cris-elf builds worked fine, but config-list.mk only builds stage > > > 1, it does not build libgfortran.
