--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
But it's not a regression since it always ICEd when the feature required was
implemented. GCC 10 rejects the code:
t.ii:6:9: error: expected nested-name-specifier before 'enum'
6 | using enum c;
| ^~~~
t.ii:9:44: error: 'd' is not a member of 'b'
9 | template <int> class e { char g = (char)b::d; };
| ^
