+ Versions 1, 2, and 3 of the operating system are derived from
+ Berkeley 4.2, meaning that you should use -opsystem=bsd4-2.
+
+ For SunOS release 4 on a Sun 3 with a 68881, use -machine=sun3-68881
+ and -opsystem=sunos4. See the file share-lib/SUNBUG for how to
+ solve problems caused by bugs in the "export" version of SunOS 4.
