--- Comment #4 from Alexander Monakov <amonakov at gcc dot gnu.org> --- > Why is it missing the static keyword then? (Or alternatively, why isn't it in > an anonymous namespace?) Huh? Without the warning developers may simply forget to put the 'static' keyword. With the warning they would be reminded when bootstrapping the patch. > Ah, I like the namespace thing for target hooks (possibly langhooks as well). Sure, it's nice to have sensible namespace rules for future additions, but hopefully that's not a reason/excuse to never re-enable the warning.
