No, they will be so on the initial call of main. Once that happens
what you do next is up to you. For example, argc will hold a
positive value on the initial call. You could use that to detect a
recursive call by passing a negative argument. It all sounds
highly purposeless though.

Stoopid program, should run and terminate:

int main(int a, char **v)
{
if (a > 0) main(-5, 0); /* do 1st recursion */
else if (a < 0) ( /* in recursive call */
/* make it known if you wish */
main(a+1, 0);
}
return 0;
}
