Do you mean functions that programs compiled by gcc may call? Or do you mean functions in the gcc compiler itself? gcc does not include very many functions that programs compiled by gcc may call. gcc is only a compiler. It does not include a library. There are a few functions implemented internally by gcc, which are documented here and in the sections following it: http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/Return-Address.html Ian
