--- Comment #5 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Eric Gallager from comment #4) > If -feliminate-unused-debug-symbols and/or -feliminate-unused-debug-types > start removing these, I'd want them to turn on -Wunused-macros automatically > for me as well so I can know about it Does the EnabledBy() thing in .opt files work across the -f/-W option prefix boundary, or are only warnings able to enable other warnings?
