+
+  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.
