  Revision 1.15  2001-07-08 21:00:18  peter
    * various widestring updates, it works now mostly without charset
      mapping supported

  Revision 1.14  2001/04/13 01:22:19  peter
    * symtable change to classes
    * range check generation and errors fixed, make cycle DEBUG=1 works
    * memory leaks fixed

  Revision 1.13  2001/04/02 21:20:37  peter
    * resulttype rewrite

  Revision 1.12  2001/03/13 11:52:48  jonas
    * fixed some memory leaks

  Revision 1.11  2000/12/25 00:07:33  peter
    + new tlinkedlist class (merge of old tstringqueue,tcontainer and
      tlinkedlist objects)

  Revision 1.10  2000/12/09 22:51:37  florian
    * helper name of val for qword fixed

  Revision 1.9  2000/12/07 17:19:46  jonas
    * new constant handling: from now on, hex constants >$7fffffff are
      parsed as unsigned constants (otherwise, $80000000 got sign extended
      and became $ffffffff80000000), all constants in the longint range
      become longints, all constants >$7fffffff and <=cardinal($ffffffff)
      are cardinals and the rest are int64's.
    * added lots of longint typecast to prevent range check errors in the
      compiler and rtl
    * type casts of symbolic ordinal constants are now preserved
    * fixed bug where the original resulttype.def wasn't restored correctly
      after doing a 64bit rangecheck

  Revision 1.8  2000/12/05 11:44:33  jonas
    + new integer regvar handling, should be much more efficient

  Revision 1.7  2000/11/29 00:30:47  florian
    * unused units removed from uses clause
    * some changes for widestrings

  Revision 1.6  2000/11/12 23:24:15  florian
    * interfaces are basically running

  Revision 1.5  2000/11/09 17:46:56  florian
    * System.TypeInfo fixed
    + System.Finalize implemented
    + some new keywords for interface support added

  Revision 1.4  2000/10/31 22:02:56  peter
    * symtable splitted, no real code changes

  Revision 1.3  2000/10/26 14:15:07  jonas
    * fixed setlength for shortstrings

  Revision 1.2  2000/10/21 18:16:13  florian
    * a lot of changes:
       - basic dyn. array support
       - basic C++ support
       - some work for interfaces done
       ....

  Revision 1.1  2000/10/15 09:33:31  peter
    * moved n386*.pas to i386/ cpu_target dir

  Revision 1.2  2000/10/15 09:08:58  peter
    * use System for the systemunit instead of target dependent

  Revision 1.1  2000/10/14 10:14:49  peter
    * moehrendorf oct 2000 rewrite
