NOTE-START
The vax (-machine=vax) runs zillions of different operating systems.
-Vax running Berkeley Unix (-opsystem=bsd4-1, -opsystem=bsd4-2 or
- -opsystem=bsd4-3)
-
- Works.
-
-Vax running Ultrix (-opsystem=bsd4-2)
-
- Works. See under Ultrix in share-lib/MACHINES for problems using X
- windows on Ultrix.
-
-Vax running System V rel 2 (-opsystem=usg5-2)
-
- 18.27 Works.
-
-Vax running System V rel 0 (-opsystem=usg5-0)
-
- Works as of 18.36.
-
-Vax running VMS (-opsystem=vms)
-
- 18.36 believed to work. Addition of features is necessary to make
- this Emacs version more usable.
