  # in.ripngd uses the ancillary data feature which is available only through
  # UNIX 98 standards version of Socket interface. This interface is supposed to
  # be accessed by -lxnet. In addition, -lsocket is used to
  # capture new not-yet-standard interfaces. Someday -lxnet alone should be enough
  # when IPv6 inspired new interfaces are part of standards.
