   The code in the #else part is wrong - it drops the colon  for  the
   -u  option,  which  causes  the  useradd command to dump core when
   built without the  WITH_SELINUX  setting.  The  code  should  read
   instead:

        ...
        +#else
        +                       getopt_long (argc, argv,
