 * Restrictions    : SHAREd items can be read/writen by usr
 *                 : EXPORTed items can only be read by usr
 *                 : PRIVATEd items cannot be read nor writen
 * Purpose         : All system dependent stuff goes here. The idea
 *                 : is that different versions of this file can be
 *                 : used to port STREAMS to other operating systems
 *                 : as well as providing a user-space testbed environment.
