COMMON: Add a header for C++11 keywords for pre-C++11 compilers. This currently adds defines for nullptr and override, so we can use them in pre-C++11 compilers, while taking advantage of them with C++11 compilers.

I don't know what that entails and I can't test it, so I err on the side of caution and only enable it in 2012 and up.
