  Revision 1.3  2002-08-09 07:33:04  florian
    * a couple of interface related fixes

  Revision 1.2  2002/07/11 14:41:32  florian
    * start of the new generic parameter handling

  Revision 1.1  2002/07/07 09:52:33  florian
    * powerpc target fixed, very simple units can be compiled
    * some basic stuff for better callparanode handling, far from being finished
