--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- >(Incidentally, it seems inconsistent that the "declared 'static' but never >defined" warning is not emitted for the class (static) member function that >also has `static` Because it really means local linkage which anonymous namespaces have. Also GCC does not warn about unused static member functions of local linkage classes.
