--- Comment #6 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
> this code should not be treated as if-else-if-else-if.

Why? It's an equivalent representation as all ifs have a return statement. =
One
another equivalent representation is:

    switch (dst_port)
    {
      case 15:
      case 23:
      case 47:
      case 45:
      case 42:
      case 1:
      case 2:
      case 3:
        return 1;
      default:
        return 0;
    }=
