HEY! CHECK THIS OUT!
The first half of this file is obsolete, and is only there to help
reconcile "what went before" with "current behavior".
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.

INFO ON NEW KERNEL PLL SYS CALLS
NTP_SYSCALLS_STD - use the "normal" ones
NTP_SYSCALL_GET - SYS_ntp_gettime id
NTP_SYSCALL_ADJ - SYS_ntp_adjtime id
NTP_SYSCALLS_LIBC - ntp_adjtime() and ntp_gettime() are in libc.
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.
STREAMS_TLI - use ioctl(I_STR) to implement ioctl(SIOCGIFCONF)
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.
MISC
USE_PROTOTYPES - Prototype functions
DOSYNCTODR - Resync TODR clock every hour.
RETSIGTYPE - Define signal function type.
LOCK_PROCESS - Have plock.
UDP_WILDCARD_DELIVERY
- these systems deliver broadcast packets to the wildcard
port instead to a port bound to the interface bound
to the correct broadcast address - are these
implementations broken or did the spec change ?
