You can say that again.  The following is valid C:

??=include <stdio.h>

int main(int ac, char *av??(??))
??<
        printf ("%s??/n", ac>1 ? av??(1??) : "No argument.");
        return 0;
??>

We don't need to check this explicitly: gcc refuses to support this
"feature" of the C/C++ standards unless given an explicit --trigraph
option.
