It does however bear the risk that projects using those features immediately lose compatibility to older compilers (which unfortunately are still common e.g. for embedded systems) -- that's especially the case if we introduce new core functionality depending on C++11.Actually, this is one of the reasons I suggested using a #define to enable Eigen's C++11 features. If one must manually define EIGEN_ENABLE_CXX11, it will remove the risk that a project begins using C++11 features without realizing it.

Another issue is that some compiler versions claim to support C++11 through their __cplusplus macro, but do not support all C++11 features.
