Summary:  gdnc daemon/file descriptor problem on NetBSD 1.6.2

Original Submission:  On NetBSD 1.6.2 gdnc fails to run: as soon as a client 
connects, it aborts. the culprit seems to be this code part:

  for (c = 0; c < FD_SETSIZE; c++)
    {
      if (is_daemon || (c != 2))
        {
          (void)close(c); 
        }
    }

it seems that too many fs's get closed and then threads break with a strange 
error message (already reported in another bug report, so almost for sure the 
two bugs are related to the same problem).

substtituting FD_SETSIZE with <= 2 works.

I never used FD_SETSIZE as in the code abce and the NetBSD manpage even states 
that FD_SETSIZE could be user set.

Alexander M. suggest to use the syscall daemon() on the system which have it to 
make the daemon. It is a BSD-style call, but linux seems to have it too.
