  Revision 1.3  2004-01-04 20:05:38  jonas
    * first working version of the Darwin/Mac OS X (for PowerPC) RTL
      Several non-essential units are still missing, but make cycle works

  Revision 1.2  2003/05/25 12:59:57  jonas
    * several fixes, addition of Mach trap numbers (thye are simply syscalls
      with a negative number)

  Revision 1.1  2002/09/08 09:00:54  jonas
    + initial revision, simply copied from FreeBSD
