When building the toolchain, one would normally use CFLAGS_FOR_TARGET and CXXFLAGS_FOR_TARGET to control the options passed to xgcc when building libstdc++. Whether this will do the right thing for your libc, I don't know. There isn't really a good way to add new options to the compiler which are automatically used, except to introduce a new configuration. Ian
