   * local browser stuff corrected

  Revision 1.10  1998/10/29 11:35:45  florian

    * bugs in secondfuncret for result in subprocedures removed

  Revision 1.8  1998/10/13 16:50:15  pierre
    * undid some changes of Peter that made the compiler wrong
      for m68k (I had to reinsert some ifdefs)
    * removed several memory leaks under m68k
    * removed the meory leaks for assembler readers
    * cross compiling shoud work again better
      ( crosscompiling sysamiga works
       but as68k still complain about some code !)

  Revision 1.7  1998/08/31 12:26:27  peter
    * m68k and palmos updates from surebugfixes

  Revision 1.6  1998/08/21 14:08:44  pierre
    + TEST_FUNCRET now default (old code removed)
      works also for m68k (at least compiles)

  Revision 1.5  1998/06/04 23:51:45  peter
    * m68k compiles
    + .def file creation moved to gendef.pas so it could also be used
      for win32

  Revision 1.4  1998/05/23 01:21:10  peter
    + aktasmmode, aktoptprocessor, aktoutputformat
    + smartlink per module $SMARTLINK-/+ (like MMX) and moved to aktswitches
    + $LIBNAME to set the library name where the unit will be put in
    * splitted cgi386 a bit (codeseg to large for bp7)
    * nasm, tasm works again. nasm moved to ag386nsm.pas

  Revision 1.3  1998/05/11 13:07:54  peter
    + $ifdef NEWPPU for the new ppuformat
    + $define GDB not longer required
    * removed all warnings and stripped some log comments
    * no findfirst/findnext anymore to remove smartlink *.o files

  Revision 1.2  1998/04/29 10:33:54  pierre
    + added some code for ansistring (not complete nor working yet)
    * corrected operator overloading
    * corrected nasm output
    + started inline procedures
    + added starstarn : use ** for exponentiation (^ gave problems)
    + started UseTokenInfo cond to get accurate positions
