Hi Edoardo.

You are using the Intel C++ Compiler, aren't you? That compiler is not yet 
fully supported by CGAL, wheras we test it daily.

That is a linker warning: it says that some libraries are passed as argument 
more than once in the linker command line. We know that issue, but we have 
not 
yet invest much time to find a solution.

Intel Compiler lookup problem. Nobody has tried yet to find a workaround.

That is a bug of TAUCS. Taucs is an external library to CGAL. We have tried 
out best to support it for a while, but that library support will probably be 
dropped by CGAL one day or another.

If you have a cross-platform patch for that issue, we will merge it in our 
repository.

That is a bug. As you can see, someone has commited a temporary change to 
that 
package, and let it goes to the release branch. :-(

Surface_reconstruction_points_3 is not yet ready to be used with MKL.
