... *without* breaking the current ABI, because if we weren't trying to keep it stable it would be much easier. If you want to you can configure with --enable-symvers=gnu-versioned-namespace and test that mode, which would allow everything to be put in something like std::__cxx2011::__8 for -std=c++11 mode, but AFAICT only one person seems to be trying that option out and giving feedback on it.
