cout and endl live in the std namespace. gcc 3.0.x enforces namespaces 
and does not automatically put everything in std into the global 
namespace. so, you either need a 

using std;

after your includes, or need to refer to cout as std::cout. AFAIK, the 
latter is preferred so as to reduce namespace pollution.
