Hi Massimiliano, >Are they free tools? I do not believe that they are free tools. >Where can I dowload them? Solbourne's AT&T C++ Cfront is US$1895 <http://www.desy.de/user/projects/C++/products/solbourne.html> Comeau C++ 4.3.3 for US$43.30 (for 43.3 day use) <http://www.comeaucomputing.com/> I have the Comeau C++ (for Amiga OS) compiler, and I've been quite happy with it. You may be able to find out more options via Google. <http://www.google.com/> HTH, --Eljay
