  12
  13   Versions 1, 2, and 3 of the operating system are derived from
  14   Berkeley 4.2, meaning that you should use -opsystem=bsd4-2.
  15
  16   If you want to use software floating point on SunOS release 4 on a
  17   Sun 3, use -machine=sun3-68881 and -opsystem=sunos4.  See the file
  18   share-lib/SUNBUG for how to solve problems caused by bugs in the
  19   "export" version of SunOS 4.
