To reserve space for 65536 bits, allocate
65536 / (sizeof(int) * CHAR_BITS) `int's instead of 65536 / (sizeof(int) * CHAR_BITS) bytes to avoid a possible segmentation fault if ports above 16383 are specified via the -p option on a platform with 4 byte wide ints. Approved by: re (bmah) Reported by: Marco Wertejuk <wertejuk@mwcis.com>
