[Bug c++/31267] #'typename_type' not supported by dump_decl#<declaration error>

I just encountered another instance of a missing typename diagnostic. This time
with a different message, so I add it here for completeness:

a.cpp:5: error: dependent-name ‘T::#‘typename_type’ not supported by
pp_cxx_unqualified_id#::DÂ’ is parsed as a non-type, but instantiation yields a
type
a.cpp:5: note: say ‘typename T::#‘typename_type’ not supported by
pp_cxx_unqualified_id#::DÂ’ if a type is meant

Testcase:

template<class T>
struct A
{
  typedef typename T::B C;
  void f() { C::D(); }
};

struct U
{
  struct B { struct D {}; };
};

void g() { A<U>().f(); }
