  17   * Specific platforms. Major release numbers differ for a good reason. So be
  18   * a good girl, plan for the future, and at least include the major release
  19   * number in the system type (for example, SUNOS5 or FREEBSD2). The system
  20   * type is determined by the makedefs shell script in the top-level
  21   * directory. Adding support for a new system type means updating the
  22   * makedefs script, and adding a section below for the new system.
