X11R4 and release 2.2 (SysV/4) for ISC 386/ix

[Guy Harris]

>486/ix (probably release 1.0) is the name for the System V.4 product

If ISC hasn't already instituted a program of drug testing, perhaps they
should start one, with the inventor of that name the first subject. 
Does that person, or another ISC employee, have an explanation why they
decided that the first digit of "386/ix" came from the "3" in "System V
Release 3", and not the "3" in "80386"? If not, they probably either:

	1) need a large red warning label indicating that "486/ix", its
	   name nonwithstanding, runs on 386 boxes (AT&T's and Intel's
	   S5R4 run on them)

or

	2) need to explain why it doesn't run on them, if for some
	   unknown reason it doesn't.
