Yes. But I hope that some thought is devoted to figuring out how this problem
can be dealt with when c++11 support is transitioned to a fully supported feature.
Eventually there would need to be one libstdc++ that programs link against and
run whether they use c++98 or c++11. I would expect there to be restrictions,
but it's a problem that eventually needs to be tackled.
