/* machine description file for Sun 68000's OPERATING SYSTEM version 2.

Note that "sun2.h" refers to the operating system version, not the

|
CPU model number. See the MACHINES file for details.

|
|
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.
