The important point here is that one might want to compile as C++11 to
benefit from optimizations (such as move constructors) whilst still
retaining a codebase compatible with older compilers. Therefore it does
make sense for c++98-compat to be active even in C++11 mode; after all, in
C++98, you would not need it!
