/* NAME
/*	sys_defs 3h
/* SUMMARY
/*	portability header
/* SYNOPSIS
/*	#include <sys_defs.h>
/* DESCRIPTION
/* .nf

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

 /*
  * 4.4BSD and close derivatives.
