  Revision 1.4  1999-07-03 00:29:50  peter
    * new link writing to the ppu, one .ppu is needed for all link types,
      static (.o) is now always created also when smartlinking is used

  Revision 1.3  1999/01/20 14:18:32  pierre
    * bugs related to mangledname solved
      - linux external without name
      -external procs already used
      (added count and is_used boolean fiels in tprocvar)

  Revision 1.2  1998/11/28 16:20:51  peter
    + support for dll variables

  Revision 1.1  1998/10/19 18:07:13  peter
    + external dll_name name func support for linux
