  $Log$
  Revision 1.3  2001-06-03 20:21:08  peter
    * Kylix fixes, mostly case names of units

  Revision 1.2  2001/02/08 13:09:03  jonas
    * fixed web bug 1396: tpointerord is now a cardinal instead of a longint,
      but added a hack in ncnv so that pointer(-1) still works

  Revision 1.1  2000/10/15 09:39:37  peter
    * moved cpu*.pas to i386/
    * renamed n386 to common cpunode

  Revision 1.5  2000/09/24 15:06:14  peter
    * use defines.inc

  Revision 1.4  2000/08/16 13:06:06  florian
    + support of 64 bit integer constants

  Revision 1.3  2000/08/12 06:45:08  florian
    + type TConstExprInt added

  Revision 1.2  2000/07/13 11:32:39  michael
  + removed logs
