But then, I'm not a C > expert, so maybe this opinion is the result of poor breeding? :-) ISO C99, 5.1.2.2.1 allows two prototypes for main: int main(void); int main(int argc, char *argv[]); GCC correctly enforces this. IMO the first is better than using __unused for both parameters, but I'm not a FreeBSD commiter :) Joerg > > Robert N M Watson
