+  The per-system SYS_* #defins ARE NO LONGER USED, with the temporary
+  exception of SYS_WINNT.
+
+  If you find a hunk of code that is bracketed by a SYS_* macro and you
+  *know* that it is still needed, please let us know.  In many cases the
+  code fragment is now handled somewhere else by autoconf choices.

+HOW TO GET IP INTERFACE INFORMATION
+
+  Some UNIX V.4 machines implement a sockets library on top of
+  streams. For these systems, you must use send the SIOCGIFCONF down
+  the stream in an I_STR ioctl. This ususally also implies
+  USE_STREAMS_DEVICE FOR IF_CONFIG. Dell UNIX is a notable exception.
+
+WHAT DOES IOCTL(SIOCGIFCONF) RETURN IN THE BUFFER
+
+  UNIX V.4 machines implement a sockets library on top of streams.
+  When requesting the IP interface configuration with an ioctl(2) calll,
+  an array of ifreq structures are placed in the provided buffer.  Some
+  implementations also place the length of the buffer information in
+  the first integer position of the buffer.
+
+  SIZE_RETURNED_IN_BUFFER - size integer is in the buffer
+
+WILL IOCTL(SIOCGIFCONF) WORK ON A SOCKET
+
+  Some UNIX V.4 machines do not appear to support ioctl() requests for the
+  IP interface configuration on a socket.  They appear to require the use
+  of the streams device instead.
+
+  USE_STREAMS_DEVICE_FOR_IF_CONFIG - use the /dev/ip device for configuration
+
+MISC
+
+  DOSYNCTODR		- Resync TODR clock  every hour.
+  RETSIGTYPE		- Define signal function type.
+  NO_SIGNED_CHAR_DECL - No "signed char" see include/ntp.h
+  LOCK_PROCESS		- Have plock.
