main() lacks a proper definition of its type. Yours is deprecated. One of
the allowed
is
int main(int,char **)

None of the two returns anything as there is no return statement, so yes,
you have a problem.
Your main() (implicitly) should return an int, but it doesn't.
int main(int argc,char **argv)
{
int result = fn1();
if (debug == 0)
fn2();
return result;
}
As I don't know what your intention is, I can only guess how the proper
main should
look like. Probably like the above.
So long,
Thomas
