This question is not appropriate for the mailing list gcc@gcc.gnu.org, which is for GCC developers. It would be appropriate for the mailing list gcc-h...@gcc.gnu.org. Please take any followups to gcc-help. Thanks. The compiler doesn't really care about main. This is more of a linker issue. If you are just looking for compilation time warnings, and you are doing the actual compilation with a different compiler, then I wouldn't worry about this. In general, the way to specify the entry point for your program is to use the linker option -e, typically via -Wl,-e,mymain. You will probably also need to use the -nostartfiles option. See the docs for those options (see the linker docs for -e). Ian
