Thanks you for your kind reply, Julian.  Unfortunately my original
note stated that I was using 1.3.3 -- the '-A' option doesn't
appear to be supported in 1.3.3 and is not mentioned in the man
page for ifconfig.

Maybe you should RTFM.

  crane:junkins {3} ifconfig -A le0
  ifconfig: illegal option -- A
  usage: ifconfig [ -m ] interface
        [ af [ address [ dest_addr ] ] [ up ] [ down ] [ netmask mask ] ]
        [ metric n ]
        [ mtu n ]
        [ arp | -arp ]
        [ media mtype ]
        [ mediaopt mopts ]
        [ -mediaopt mopts ]
        [ link0 | -link0 ] [ link1 | -link1 ] [ link2 | -link2 ]
       ifconfig -a [ -m ] [ -d ] [ -u ] [ af ]
       ifconfig -l [ -d ] [ -u ]
  crane:junkins {4}
