Oh.. *that* little bug.  It drove me bonkers while trying to get
AIX/370 and xntp to cooperate.  Here's the fix I used to work
around it:

*** ntp_io.c.dist       Tue Mar 17 16:39:15 1992
--- ntp_io.c    Tue Mar 17 16:40:26 1992

*** 688,693 ****
--- 688,694 ----
                printf("sendpkt(%s, %s, %d)\n", ntoa(dest),
                        ntoa(&inter->sin), len);
  #endif
+       if (inter == any_interface) inter++;

        for (slot = ERRORCACHESIZE; --slot >= 0; )
                if (badaddrs[slot].port == dest->sin_port &&


This basically prevents xntpd from "seeing" the 'wildcard' interface.
