struct Base
{
template <class T>
struct Kind

typedef T type;

struct Derived : public Base { };
template <>
struct Derived::Kind<char> // Should fail to compile here

typedef int type;

int main(void) { }
I believe the above code should be rejected but gcc 4.1.2 accepted it. Global
scope explicit member template specialization of the inner struct Kind is shown
to be in the Derived class. (It is rejected by Comeau). gcc correctly rejects
in the case of member template functions but not in case of structs/classes.
