Inner specialization

[zolee69]

Hi all!

I'm trying to make an inner template specialization. My MSVC 7.0 compiler doesn't really like it, ends with an internal error.
I'd like to ask you if this is a legal declaration.

template <typename T> struct D;

template <typename T> struct R
{
    struct A
    {
        T m;
    };
    template<> struct D<A>
    {
    };
    D<A> v;

};

If not, can somebody help me with a workaround tip?
Thanks!
