Optimized C code

Dear /prog/, how can I further optimize this piece of code to make it ENTERPRISE ? :

int main(void){
 return(main());
}

None of you are checking whether 'main' exists before calling it. You never know, it could be a NULL pointer and cause the whole program to crash.

[code]
int main(void) {
    while (fork()) {
        assert(main != NULL);
        main();
    }
}
