--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
All your examples are missing a semi-colon after the struct definition.

The corrected last example is:

struct A
{
    template <int, int> struct Inner;
    template <int i> struct Inner<0, i> {};
};

struct B: A
{
    template <int, int> struct Inner; // OK, shadows declaration in A
    template <int i> struct Inner<0, i> {};

    template <int, int> struct Inner; // Fail, redeclaration.
};
