	Shouldn't line number 7 in X11/Xlibos.h be

	#ifdef SYSV

	instead of

	#ifdef att


Possibly, but not necessarily.  There are 4 symbols used in R4 for System
V-ish things:

	SYSV			SVR2 systems

	USG			SVR3 systems

	att			AT&T 6386 running V.3.2 ("pure UNIX"?)

	STREAMSCONN		tli connection

The block in question probably has more to do with STREAMSCONN than USG (SYSV
is for earlier derivatives), although our System V expertise is limited to
HP-UX, A/UX, UNICOS, and System V Release 3.2 on the 6386.  Suggestions from
people with more experience with SVR3 and and later are always welcome.

With System V Release 4, there will be undoubtedly be additional hacking
(we're currently planning to use the symbol SVR4 unless there is a new builtin
cpp symbol :-).
