  32   reconcile "what went before" with "current behavior".
  33
  34   The per-system SYS_* #defins ARE NO LONGER USED, with the temporary
  35   exception of SYS_WINNT.
  36
  37   If you find a hunk of code that is bracketed by a SYS_* macro and you
  38   *know* that it is still needed, please let us know.  In many cases the
  39   code fragment is now handled somewhere else by autoconf choices.

  52 HOW TO GET IP INTERFACE INFORMATION
  53
  54   Some UNIX V.4 machines implement a sockets library on top of
  55   streams. For these systems, you must use send the SIOCGIFCONF down
  56   the stream in an I_STR ioctl. This ususally also implies
  57   USE_STREAMS_DEVICE FOR IF_CONFIG. Dell UNIX is a notable exception.
  58
  59 WHAT DOES IOCTL(SIOCGIFCONF) RETURN IN THE BUFFER
  60
  61   UNIX V.4 machines implement a sockets library on top of streams.
  62   When requesting the IP interface configuration with an ioctl(2) calll,
  63   an array of ifreq structures are placed in the provided buffer.  Some
  64   implementations also place the length of the buffer information in
  65   the first integer position of the buffer.
  66
  67   SIZE_RETURNED_IN_BUFFER - size integer is in the buffer
  68
  69 WILL IOCTL(SIOCGIFCONF) WORK ON A SOCKET
  70
  71   Some UNIX V.4 machines do not appear to support ioctl() requests for the
  72   IP interface configuration on a socket.  They appear to require the use
  73   of the streams device instead.
  74
  75   USE_STREAMS_DEVICE_FOR_IF_CONFIG - use the /dev/ip device for configuration
  76
  77 MISC

  79   DOSYNCTODR            - Resync TODR clock  every hour.
  80   RETSIGTYPE            - Define signal function type.
  81   NO_SIGNED_CHAR_DECL - No "signed char" see include/ntp.h
  82   LOCK_PROCESS          - Have plock.
