You should use C3t3::Triangulation::Facet as Id type. The type Facet is 
mutable.

Here, replace with 

  typedef typename C3t3::Facet_iterator Facet_iterator;
  typedef typename C3t3::Triangulation::Facet Id;

Here replace with:

AABB_mesh_3_triangle_primitive(Facet_iterator fit)
  : m_facet_handle( *fit )

And rename m_facet_handle to m_facet.
