#include <vector>
-------------------------------------------------------------------------------
using namespace std;

template <class T>
struct coord_vector {
  };

template<class T>
struct polygon_segment : public vector<coord_vector<T> > {
    void insert_c(iterator it);
  };

-------------------------------------------------------------------------------
	This file results in a parse error in the "insert_c" line, though
	it should probably find the superclass's iterator. The problem goes
	away if coord_vector is a non-template.
>How-To-Repeat:
	
>Fix:
	qualify "iterator" with superclass name
