According to the C Standard, main can be either:

int main(void);
-or-
int main(int argc, char *argv[]);

void main(void) is ILLEGAL!  Some compilers also allow:

int main(int argc, char *argv[], char *env);

Or something like that, but that is considered an implementation extention and
is not portable.

Don't know about this one.  See Damian and Eli's responses.
