This is the problem, but it's not a user problem. __gnu_debug::list is a 
wrapper around __gnu_norm::list, so both implementations need to coexist 
otherwise the debug mode won't compile. So each debug-mode class template 
looks like:

namespace __gnu_debug {
  template<typename T, typename Allocator = std::allocator<T> >
    class list : public __gnu_norm::list<T, Allocator>
    {
      // ...
    };
}
