No. Somebody has to do the work. It will get into GCC if somebody does the work, but not before then. > The most complex part is probably the implementation of the commandline > argument and (esp.) getting the build system to use -stdlib=libstdc++ if I still think that should be the default, on all targets. > that's indeed required to build GCC itself.
