 Reconfirmed on 2.95 -> 3.3 20030401. The code does look legit to me in fact.
 Can anybody test it with the mainline? It really looks like a parsing bug.

>Description:
The code in "How-To-Repeat" is legal, to the best of my knowledge. However, it fails to compile with the following error:

tTemplate.cc:19: no `Templated<T>::NonTemplated::operator std::vector<T, 
   std::allocator<_CharT> >::size_type() const' member function declared in 
   class `Templated<T>::NonTemplated'
tTemplate.cc:19: template definition of non-template `
   Templated<T>::NonTemplated::operator std::vector<T, std::allocator<_CharT> 
   >::size_type() const'
>How-To-Repeat:
#include <vector>

template <class T>
class Templated
{
private:
  typedef std::vector<T> buf_t;
  class NonTemplated
  {
  public:
    operator typename buf_t::size_type() const;
  private:
    typename buf_t::size_type myIndex;
  };
};

template <class T>
Templated<T>::NonTemplated::operator typename Templated<T>::buf_t::size_type() const
{
  return myIndex;
}


int main()
{
  Templated<int> tmpl;
  return 0; 
}
