--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- I think it's referring to control-flow problems and data-flow problems, but maybe I'm wrong about that. I'm not sure what a warning about control is, but I know what control flow is Also, I think the original was about warnings that are _sensitive to_ control-flow and data-flow, not necessarily warnings _about_ control-flow and data-flow. Although I can't think of any examples of warnings sensitive to control-flow or data-flow where you couldn't argue that they are also about those. So maybe it doesn't matter.
