I think the best thing to do is autodetect the parallel port.  Have to
do something like this:

  if (q->port == 0) {
    int *portptr = {0x378, 0x278, 0x3bc, 0};

    while(*portptr) {
      q->port = *portptr++;
      if (qc_open(q)) {
	if (qc_detect(q))
	  break;
	qc_close(q);
      }
    if (*portptr) {
      fprintf(stderr, "Can't autodetect the QuickCam -- you may need"
              "to explicitly set the parallel port address.\n");
      exit(1);
    }
  }
