I've tested with the following typedef's:
typedef CGAL::Gmpq NT;
typedef CGAL::Cartesian<NT> Kernel;
typedef CGAL::Nef_polyhedron_3<Kernel, CGAL::SNC_indexed_items>
Nef_polyhedron_3;
But I was still given an "Constructor not available for this Kernel" warning
when the N.intersection(Plane_3(a,b,c,d)) function was called.
For the case that I use the default items type, instead of the indexed items
type,
in typedef'ing Nef_3, i.e.:
typedef CGAL::Nef_polyhedron_3<Kernel> Nef_polyhedron_3;
the result was identical.
