--------------------------------

  /* Compile options needed: none
  */ 
  #include <iostream.h>
  template <class T> class genvec3d { };
  template <class T>
  ostream& operator<< (ostream& o, const genvec3d<T>& p)
  {
     return o;
  }
  class ray
  {
     public:
                  genvec3d<float> origin;
                  ray(){}
                  friend int operator<<(ostream& o, ray& r)
  /* The following line causes compiler Error */ 
                  { o << origin; return 1; }

  /* To work around the problem, change the line above into a comment and
     change the following line to an executed line of code.  */ 
              /*  { o << r.origin; return 1; }  */
