- /* The following line tells the configuration script what sort of
- operating system this machine is likely to run.
- USUAL-OPSYS="note"
-
- NOTE-START
- Sun 1, 2 and 3 (-machine=sun1, -machine=sun2, -machine=sun3;
- -opsystem=bsd4-2 or -opsystem=sunos4)
-
- Whether you should use sun1, sun2 or sun3 depends on the
- VERSION OF THE OPERATING SYSTEM
- you have. There are three machine types for different versions of
- SunOS. All are derived from Berkeley 4.2, meaning that you should
- use -opsystem=bsd4-2. Emacs 17 has run on all of them. You will
- need to use sun3 on Sun 2's running SunOS release 3.
-
- For SunOS release 4 on a Sun 3, use -machine=sun3 and
- -opsystem=sunos4. See the file share-lib/SUNBUG for how to solve
- problems caused by bugs in the "export" version of SunOS 4.
