    Revision 1.5  1998-09-04 08:49:07  peter
      * 0.99.5 doesn't compile a whole objpas anymore to overcome crashes

    Revision 1.4  1998/08/10 15:52:27  peter
      * fixed so 0.99.5 compiles it, but no exception class

    Revision 1.3  1998/07/29 15:44:32  michael
     included sysutils and math.pp as target. They compile now.

    Revision 1.2  1998/04/10 15:18:21  michael
    Added a lot of functions donated by GertJan Schouten

    Revision 1.1.1.1  1998/03/25 11:18:49  root
    * Restored version

    Revision 1.1  1998/02/05 11:11:32  michael
    + moved to objpas directory

    Revision 1.2  1998/02/03 15:27:25  florian
    *** empty log message ***

    Revision 1.1  1998/02/01 23:32:01  florian
