Oh, and I did not realize in my first mail, but Filtered_exact is  now
completely gone (this must indeed be a very old program that you have here !).

You should try to replace something like :

  #include <CGAL/Filtered_exact.h>
  typedef CGAL::Filtered_exact<double, CGAL::MP_Float> NT;
  typedef CGAL::Cartesian<NT>  K;

by :

  #include <CGAL::Exact_predicates_inexact_constructions_kernel.h>
  typedefCGAL::Exact_predicates_inexact_constructions_kernel K;

If you do not succeed, please provide more details about your problem
(error messages, more code pieces).
