I ran into exactly the same problem I assume Xin Li is now running into just a few days ago: gcc warns if argc and argv are unused in the main() definition if they aren't referenced when running at higher WARNS levels. I would argue this is a bug in gcc, since main() is part of an API calling convention, and it doesn't matter if the arguments are unused by the function -- they are still provided by the caller. But then, I'm not a C expert, so maybe this opinion is the result of poor breeding? :-) Robert N M Watson
