--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- I'd prefer if the compiler just got it right. This seems like a warning that should fire even in system headers. Or it should track that the value is a function parameter and came from a non-system header and so the diagnostic location should not consider the point of use.
