Yep, just I first read the text as /usr/include/c++ itself being in
the include path (which it is not). Of course, g++-v3 is even more
incorrecot :-), so the patch is fine.
Perhaps you can rephrase it a bit to help clarify that? (But that
is optional; in any case, your patch improves what is currently there.)
