--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Also accepts:
```
struct outer
{
    template <typename T = long>
    struct inner;
};

template <typename T = long>
struct outer::inner{};
```
But that is a regression. Let me file that seperately but related issue.

Otherwise confirmed.
