  $Log$
  Revision 1.2  2003-05-25 13:51:58  jonas
    * several fixes, addition of Mach trap numbers (thye are simply syscalls
      with a negative number)

  Revision 1.6  2003/05/23 21:58:30  jonas
    * fixed storing to errno for single threaded programs

  Revision 1.5  2003/05/11 16:07:55  jonas
    * fixed mmap for non-i386 non-m68k architectures (not sure about
      x86-64)

  Revision 1.4  2003/04/22 17:07:55  florian
    * there where two SYSCALL1 procedures for the powerpc, fixed

  Revision 1.3  2003/01/09 13:38:26  florian
    * syscall stuff fixed

  Revision 1.2  2002/12/22 16:00:28  jonas
    + added syscallh.inc, adapted syscall.inc

  Revision 1.1  2002/11/09 20:32:14  marco
   * powerpc version. Threadsafe errno access not yet done.

  Revision 1.1  2002/10/14 19:39:44  peter
