>Description:
Look at this:

---------------------------------------
template <class T>
struct A
{
};

struct B
{
};


template <class T> 
A<T>::k func1(); 

B::k func2();
---------------------------------------
pr10615.cpp:12: error: expected function-definition
pr10615.cpp:14: error: expected constructor, destructor, or type conversion
pr10615.cpp:14: error: expected `,' or `;'

(note: this code ICEs on 3.3, but there's already a PR for it, c++/10617)

I think the error message should be improved since it is
a bit confusing right now. This is for instance what I get with Comeau/EDG on the same snippet:


"pr10615.cpp", line 12: error: nontype "A<T>::k [with T=T]" is not a type name
  A<T>::k func1();
  ^

"pr10615.cpp", line 14: error: class "B" has no member "k"
  B::k func2();
     ^

Compile the above code
