--- Comment #6 from René J.V. Bertin <rjvbertin at gmail dot com> --- (In reply to Richard Biener from comment #5) > Confirmed. Meaning "that G++ will one day have this kind of support for libc++"? Is there a timeline or something? The most complex part is probably the implementation of the commandline argument and (esp.) getting the build system to use -stdlib=libstdc++ if that's indeed required to build GCC itself. But even that must be trivial for developers who know their way around those waters.
