Hi,

I have been using Exact_predicates_exact_constructions_kernel with CGAL-3.0.1 
without problems. Recently, I have switched to CGAL-3.2.1 and my code does 
not compile any more.

The part of the code that does not compile is as follows

.
.

#include <CGAL/Exact_predicates_exact_constructions_kernel.h>

.
.

typedef CGAL::Exact_predicates_exact_constructions_kernel<double> Kernel;


The compiler issues the following error message

buildcrack_cgal.h:115:* error:  
CGAL::Exact_predicates_exact_constructions_kernel is not a template*

I took a look at the CGAL/Exact_predicates_exact_constructions_kernel.h in 
which we have

typedef Filtered_kernel<Simple_cartesian<Lazy_exact_nt<Quotient<MP_Float> > > 
>
        Exact_predicates_exact_constructions_kernel;

So, I tried:

#include <CGAL/Simple_cartesian.h>
#include <CGAL/Filtered_kernel.h>
#include <CGAL/Lazy_exact_nt.h>
typedef 
CGAL::Filtered_kernel<CGAL::Simple_cartesian<CGAL::Lazy_exact_nt<CGAL::Quotient<realType>
 > > > Kernel

It works but it does not compile other parts of the code. 

I also tried to compile with Simple_Cartesian and it compiles without 
problems but I need to used Exact_predicates_exact_constructions_kernel in my 
code.

By the way, I am using  *g++ (GCC) 4.1.2 20061115 (prerelease) (SUSE Linux).

*Does anyone know why I'm having this problem?

Thanks a lot!
