Help? You neglected to mention which version of gcc you are using. A cast from a a pointer to an integer of smaller size is forbidden by the C++ language standard. Gcc reports this type of violation as an error by default. You can tell gcc to permit this kind of thing by using the -fpermissive option. Ian
