* MACHINES: Update description of SYSVr3 and r4 support, due to
	Eric Raymond's changes.

	* MACHINES: Mention that you have to edit the configure script
	when you add support for a new machine, to get it to recognize the
	configuration name.

If you add support for a new configuration, add a section to this

You may have to add ANSI idempotence #-lines to your sys/types.h
file to get Emacs to compile correctly. This may be necessary on
other pre-ANSI systems as well.
Supported, including shared libraries for ELF, but ptys do not

On an AT&T 6386WGS using System V Release 3.2 and X11R3, the X support
cannot be made to work. Whether or not the GNU relocating malloc is
used, the symptom is that the first call Emacs makes to sbrk(0) returns
(char *)-1. Sorry, you're stuck with character-only mode. Try
installing Xfree86 to fix this.
System V rel 4.0.3 and 4.0.4 (usg5.4)
Supported, including shared libraries for ELF, but ptys do not work
because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have
fixed this). This failure is probably due to a misunderstanding of
the consequences of the POSIX spec: many system designers mistakenly
think that POSIX requires this feature to fail. This is untrue;
ptys are an extension, and POSIX says that extensions *when used*
may change the action of standard facilities in any fashion.

Some versions 3 and earlier of V.4, on the Intel 386 and 860, had
problems in the X11 libraries. These prevent Emacs from working
with X. You can use Emacs with X provided your copy of X is based
on X11 release 4 or newer. Unfortunately, the only way you can tell
whether your X11 library is new enough is to try compiling Emacs to
use X. If xemacs runs, your X11 library is new enough.

In this context, GSV4 and GSV4i are alternate names for X11R4.
