--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> --- As Jakub notes, it's a deletion fix-it hint. It's suggesting the deletion of the same range as that of the primary location of the diagnostic, so arguably there's some redundancy there. I wonder if there's a better way to present this information, but I don't have any ideas at the moment.
