These configurations break enough that I doubt anybody is depending on
them. I think I would have seen more bug reports if people were trying to
use it.

This is also the entirely wrong question to ask. What's important is that
Libc++ is allowed to required C++11, and C++11 implementation should work.
People who insist on using a ToT STL with an old compiler puzzle me. You
can't expect new library features without additional language support.
