Hi!

I use the "Exact_predicates_exact_constructions_kernel" Kernel and I
need the sqrt function. The manual told me to use the
Exact_predicates_exact_constructions_kernel_with_sqrt kernel and now I
get the following compile error:

These are the relevant typedefs:

typedef CGAL::Exact_predicates_exact_constructions_kernel_with_sqrt K;
//typedef CGAL::Exact_predicates_exact_constructions_kernel K;

typedef K::FT dbl;

typedef CGAL::Regular_triangulation_filtered_traits_2<K>
TriangulationTraits;
typedef CGAL::Regular_triangulation_2<TriangulationTraits>
Regular_triangulation;

typedef Regular_triangulation::Weighted_point Rt_Weighted_point;
typedef Regular_triangulation::Vertex_handle Rt_Vertex_handle;
typedef Regular_triangulation::Bare_point Rt_Point;
typedef Regular_triangulation::Segment Rt_Segment;

typedef Regular_triangulation::Edge_circulator Rt_Edge_circulator;
typedef Regular_triangulation::Vertex_circulator Rt_Vertex_circulator;
typedef Regular_triangulation::Finite_vertices_iterator
Rt_Finite_vertices_iterator;
typedef Regular_triangulation::Finite_edges_iterator
Rt_Finite_edges_iterator;
typedef Regular_triangulation::Hidden_vertices_iterator
Rt_Hidden_vertices_iterator;
typedef Regular_triangulation::All_edges_iterator  Rt_All_edges_iterator;
typedef Regular_triangulation::All_vertices_iterator
Rt_All_vertices_iterator;
typedef Regular_triangulation::Edge_iterator Rt_Edge_iterator;
typedef Regular_triangulation::Face_handle Rt_Face_handle;
typedef Regular_triangulation::Locate_type Rt_Locate_type;

typedef K::Vector_2 Vector;
typedef K::Ray_2 Ray;
typedef K::Line_2 Line;
typedef CGAL::Point_2<K> Point;

Whats wrong?
