Hello,


I use a std::map<,> in my code,
and received a message as follows.
< Error message

*****************************************************************
I think this error is related to overloading the operator '<' in CGAL.


All of the code is long, so I'll show a part of it.
I skipped many parts of code which I consider they mean nothing to this 
problem.

< A part of codes 
>**************************************************************
...
struct ControlPointsOfFacet{
Point p[ 10 ];
};
...

class Surface{
public:
 Polyhedron surfaceMesh;
 std::map< FacetIterator, ControlPointsOfFacet > controlPoint;
...
}
...



...( in another member function of class Surface )
Surface surface;
...
FacetIterator fit = surface.surfaceMesh.facets_begin();
...
ControlPointsOfFacet cp;
cp.p[0]=Point(...);
...
cp.p[9]=Point(...);
...
controlPoint.insert( std::make_pair( fit, cp ) );
...

How can I fix this problem?
