  $Log$
  Revision 1.8  2002-12-29 15:30:55  peter
    * updated for 1.1 compiler that does not allow calling conventions
      for constructor/destructor

  Revision 1.7  2002/12/05 15:54:20  pierre
   * update as openstrings are transformed into normal string in cdecl'ared functions

  Revision 1.6  2002/11/20 19:39:21  carl
  - high() cannot be used in cdecle'd routines

  Revision 1.5  2002/11/09 21:47:37  carl
    + updated tests for correct parsing (array of const now allowed with high!)

  Revision 1.4  2002/09/22 09:08:41  carl
    * gets64bit was not returning an int64!

  Revision 1.3  2002/09/07 15:40:55  peter
    * old logs removed and tabs fixed

  Revision 1.2  2002/05/13 13:45:38  peter
    * updated to compile tests with kylix

  Revision 1.1  2002/04/13 17:51:00  carl
  + var parameter passing for different calling conventions
