  * System calls are transformed into request messages to the SYS task that is 
  * responsible for handling the call. By convention, sys_call() is transformed 
  * into a message with type SYS_CALL that is handled in a function do_call(). 
+ * 
+ * Changes:
+ *   Jul 30, 2005   created SYS_INT86 to support BIOS driver  (Philip Homburg) 
+ *   Jul 13, 2005   created SYS_PRIVCTL to manage services  (Jorrit N. Herder) 
+ *   Jul 09, 2005   updated SYS_KILL to signal services  (Jorrit N. Herder) 
+ *   Jun 21, 2005   created SYS_NICE for nice(2) system call  (Ben J. Gras)
+ *   Jun 21, 2005   created SYS_MEMSET to speed up exec(2)  (Ben J. Gras)
+ *   Apr 12, 2005   updated SYS_VCOPY for virtual_copy()  (Jorrit N. Herder)
+ *   Jan 20, 2005   updated SYS_COPY for virtual_copy()  (Jorrit N. Herder)
+ *   Oct 24, 2004   created SYS_GETKSIG to support PM  (Jorrit N. Herder) 
+ *   Oct 10, 2004   created handler for unused calls  (Jorrit N. Herder) 
+ *   Sep 09, 2004   updated SYS_EXIT to let services exit  (Jorrit N. Herder)
