Here the problem is that we aren't detecting a NSDMI in C++98:

};
because maybe_warn_cpp0x uses input_location and that happens to point
to NULL which comes from a system header. Jakub suggested changing the
location to the '=', thereby avoiding the system header pro

In an effort to avoid false positives while still detecting

PHI nodes chooses the operand with the most space remaining
