Thanks for the pointer. Yes, this helps one step further :) And, this also means that USES=compiler:C++11-lang provides anything gcc specific? Then it would also be unnecessary to use USE_CXXSTD=gnu++11 instead of USE_CXXSTD=c++11? Sorry if this should have been clarified already and I just didn't understand it yet.
