 1.2   17.11.99 : added VBCC
 1.3   29.02.00 : fixed VBCC REG define
 1.4   30.03.00 : fixed SAVEDS for VBCC
 1.5   29.07.00 : added #undef statements (needed e.g. for AmiTCP together
        with vbcc)
 1.6   19.05.01 : added STACKEXT and Dice stuff
 1.7   16.06.02 : added MorphOS specials and VARARGS68K
 1.8   21.09.02 : added MorphOS register stuff
 1.9   26.09.02 : added OFFSET macro. Thanks Frank Wille for suggestion
 1.10  18.10.02 : reverted to old MorphOS-method for GCC
 1.11  09.11.02 : added REGARGS define to MorphOS section
 1.12  21.01.04 : added SDI_MORPHOSNOREG define to change behaviour
 1.13  23.05.04 : added machine definitions

/* Define SDI_MORPHOSNOREG in your makefile to switch register based functions
   to normal C-Style functions as it is default for PPC. */

** This is PD (Public Domain). This means you can do with it whatever you want
** without any restrictions. I only ask you to tell me improvements, so I may
** fix the main line of this files as well.

** To keep confusion level low: When changing this file, please note it in
** above history list and indicate that the change was not made by myself
** (e.g. add your name or nick name).
