  Revision 1.53  1998/09/30 16:43:36  peter
    * fixed unit interdependency with circular uses

  Revision 1.52  1998/09/28 16:57:22  pierre

      to get it work with and without ansistrings

  Revision 1.51  1998/09/26 17:45:30  peter
    + idtoken and only one token table

    + aktmodeswitches

  Revision 1.49  1998/09/23 15:39:07  pierre
    * browser bugfixes
      was adding a reference when looking for the symbol
      if -bSYM_NAME was used

  Revision 1.48  1998/09/22 17:13:48  pierre
    + browsing updated and developed
      records and objects fields are also stored

  Revision 1.47  1998/09/21 09:00:18  peter
    * reset_gdb_info only when debuginfo is set

  Revision 1.46  1998/09/21 08:45:12  pierre
    + added vmt_offset in tobjectdef.write for fututre use
      (first steps to have objects without vmt if no virtual !!)
    + added fpu_used field for tabstractprocdef  :
      sets this level to 2 if the functions return with value in FPU
      (is then set to correct value at parsing of implementation)
      THIS MIGHT refuse some code with FPU expression too complex
      that were accepted before and even in some cases
      that don't overflow in fact
      ( like if f : float; is a forward that finally in implementation
       only uses one fpu register !!)
      Nevertheless I think that it will improve security on
      FPU operations !!
    * most other changes only for UseBrowser code
      (added symtable references for record and objects)
      local switch for refs to args and local of each function
      (static symtable still missing)
      UseBrowser still not stable and probably broken by
      the definition hash array !!

    + improvement on the usebrowser part
      (does not work correctly for now)

    * UseBrowser a little updated (might still be buggy !!)
    * bug in psub.pas in function specifier removed
    * stdcall allowed in interface and in implementation
      (FPC will not yet complain if it is missing in either part
      because stdcall is only a dummy !!)
