Hm. Our GCC package initially bootstraps without libstdc++ support...

I think there are now various C++ 'helper' libraries bundled with GCC that require C++ to be built, e.g. libcody, so I assume libstdc++ is needed to build these. >> We should team up an get this done!

OK, please ping me when you've had a chance to look at my work above or some work of your own I could look at. -- Thanks, Maxim
