Well, there is the difference. g++ may support C++11 constructs and libstdc++
should be able to use them, but it's wrong to announce __cplusplus == 201103L
to the operating system's headers until it actually does support C++11.
But it could well be the case that changing fixincludes to do the right thing
is sufficient.
