Manuel López-Ibáñez <manu at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |easyhack --- Comment #3 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- It seems pretty straight-forward: 1. Abstract out the check for classification_history. 2. Create a function diagnostic_report_warnings_p that checks the classification history of Wsystem-headers in addition to the option value. Not that -Wsystem-headers is not a typical warning option, so more work would be needed to have #pragma GCC diagnostic error "-Wsystem-headers" give errors instead of warnings or -Werror #pragma GCC diagnostic warning "-Wsystem-headers" give warnings instead of errors. But that seems less important to fix.
