I have made a comparison in this matter.

  Glibc:   rcmd,    rresvport,    ruserok,    iruserok
           rcmd_af, rresvport_af, ruserok_af, iruserok_af

  *BSD:    rcmd,    rresvport,    ruserok,    iruserok
           rcmd_af, rresvport_af,   --,          --
                                              iruserok_sa

  Solaris: rcmd,    rresvport,    ruserok,       --
           rcmd_af, rresvport_af,   --,          --
                    rresvport_addr

As can be seen the extensions to get address family independence
vary to full extent. Would there be a great loss, as a first step,
to replace iruserok() with ruserok() in Solaris?

Best regards,
