            Bug ID: 10991
           Summary: getops error in nc if compiled without NC_SERVER
           Product: Busybox
           Version: 1.28.x
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: Networking
          Assignee: unassigned at busybox.net
          Reporter: frank.vosseler at microfocus.com

  Target Milestone: ---

We have built BB without NC_SERVER, i.e. without the '-l' option enabled. 
However, when we run nc (e.g. 'nc -vz google.com 80'), we get an error "nc: NO
OPT l!"

I suspect this is because the complementary options in nc_bloaty.c define the
'l' option unconditionally in line 794 by mistake:
    790  getopt32(argv, "^"
    791                 "np:s:uvw:+"/* -w N */ IF_NC_SERVER("lk")
    792                 IF_NC_EXTRA("i:o:z")
    793                         "\0"
    794                         "?2:vv:ll", /* max 2 params; -v and -l are
counters */

Line 794 should define the complementary option l conditional on NC_SERVER:
"?2:vv" IF_NC_SERVER(":ll"), /* max 2 params; -v and -l are counters */
