 Notice that the code is not legal C++. The snippet reported by Reichelt is:
 
 ------------------------snip here------------------------
 template <typename T, typename U> struct A
  {
      template <typename V> class SubA {};
  };
 
  template <typename T> struct B : public A<T,int>::SubA<int> {};
 
  B<int> b;
  ------------------------snip here------------------------
 
 which is not legal C++, because it's accessing a nested template without the
 explicit template keyword. The correct version:
 
 ------------------------snip here------------------------
  template <typename T> struct B : public A<T,int>::template SubA<int> {};
 ------------------------snip here------------------------
 
 which correctly compiles on my GCC 3.1. So the PR type should be changed to
 ice-on-illegal-code. This should also solve the reporter's compilation
 problems.
