--Apple-Mail=_5FB184A3-F259-451A-ABB9-6ECD41797338 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 Thanks Mark. :( Is cc1plus the g++ compiler that is installed on your bootstrapped = system, or is it the one that the powerpc64-gcc toolchain built? cc1plus = -v will help determine that. You may have to find it on your system = (there=E2=80=99s likely 2) and pass it the -std=3Dc++11 option to see = which of them fail. We may have a leak / problem with mkdep that your = unique setup is revealing.
