C++11 support is available.
This is a very dodgy way of checking - haven't tested across compilers very well, and it doesn't take into account the partial completeness of the implementations.
It does however, provide a way for headers to use c++11 symbols in a non-destructive way for users (we often define typedefs for shared ptr variations).
