/* The following line tells the configuration script what sort of
operating system this machine is likely to run.
USUAL-OPSYS="note"
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.
