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