Hi!

I have 2 types of triangulation in my application:

* Delaunay
* Regular

I define them like this:

typedef CGAL::Regular_triangulation_euclidean_traits_3<K> Traits;
typedef CGAL::Triangulation_vertex_base_with_info_3<int, Traits> Vb;
typedef CGAL::Regular_triangulation_cell_base_3<Traits> 
 CbBase;
typedef CGAL::Triangulation_cell_base_with_info_3<RTCellState, Traits, 
CbBase> Cb;
typedef CGAL::Triangulation_data_structure_3<Vb, Cb> 
 Tds;
typedef CGAL::Regular_triangulation_3<Traits, Tds> Regular_triangulation;

and:

typedef CGAL::Triangulation_vertex_base_with_info_3<int, Traits> DVb;
typedef CGAL::Triangulation_cell_base_with_circumcenter_3<K> DCb;
typedef CGAL::Triangulation_data_structure_3<DVb, DCb>       DTDS;
typedef CGAL::Delaunay_triangulation_3<K, DTDS> 
Delauny_Triangulation;
typedef Delauny_Triangulation::Vertex_handle          Dt_Vertex_handle;

I have added some cell info to the regular triangulation. The class is 
called "RTCellState" and one member of it is a "Dt_Vertex_handle".
If I define the Delaunay Triangulation before I include the 
RTCellState.h" everything works fine as it should. Now I have an issue 
with extending the Delaunay_Vertex_Base with some info about the 
Regular_Triangulation::Facet.

So, if I change the line:
typedef CGAL::Triangulation_vertex_base_with_info_3<int, Traits> DVb;

to:
typedef 
CGAL::Triangulation_vertex_base_with_info_3<Regular_triangulation;::Facet, 
Traits> DVb;

I do get compiler errors. Any ideas to handle this case? I need both 
references:

From a Delaunay Vertex an info about some RegularTriang. Facet and then 
second reference from a RegularTriang. Cell to some Delaunay Vertex Handles.

Please help! :-) TIA,
Thomas
