I am writing to see if it is possible to make_pair of Triangle_3 with
additional property, such that I use the following typedefs: 

- typedef CGAL::Simple_cartesian<double> Kernel; 
- typedef Kernel::FT FT; 
- typedef Kernel::Point_3 Point; 
- typedef Kernel::Triangle_3 Triangle; 
- typedef std::vector<std::pair&lt;Triangle,char*>>::iterator Iterator; 
- typedef CGAL::AABB_triangle_primitive<Kernel, Iterator>
AABB_triangle_Primitive; 
- typedef CGAL::AABB_traits<Kernel, AABB_triangle_Primitive>
AABB_triangle_traits; 
- typedef CGAL::AABB_tree<AABB_triangle_traits> AABB_triangle_Tree; 

The triangle tree builds successfully in visual studio, but if I add the
next line of code: 

- AABB_triangle_tree.accelerate_distance_queries(); 

or if I try to use the tree, such as a computation of a triangle distance to
a point, for example: 

- AABB_triangle_tree.squared_distance(points[i])) 

the code does not compile successfully, with the following error: 

"Error  2       error C2664: 'const CGAL::Point_3<R_>
&CGAL::CommonKernelFunctors::Construct_vertex_3<K>::operator ()(const
CGAL::Tetrahedron_3<R_> &,int) const' : cannot convert parameter 1 from
'std::pair<_Ty1,_Ty2>' to 'const CGAL::Tetrahedron_3<R_> &'
C:\dev\CGAL-4.9\include\CGAL\AABB_triangle_primitive.h  47      1       
ptDiffTest" 

It is possible to make pair with point, for example, using: 

- std::vector< std::pair<Point, unsigned> > points; 

Is it not possible to do the same with Triangle. Thank you for your support.
Kind Regards, DC.
