    * some defines to exclude some compiler parts

  Revision 1.17  1998/06/04 23:52:04  peter
    * m68k compiles
    + .def file creation moved to gendef.pas so it could also be used
      for win32

  Revision 1.16  1998/06/01 16:50:22  peter
    + boolean -> ord conversion
    * fixed ord -> boolean conversion

  Revision 1.15  1998/05/30 14:31:11  peter
    + $ASMMODE

  Revision 1.14  1998/05/29 13:24:45  peter
    + asw assembler

  Revision 1.13  1998/05/27 00:20:33  peter
    * some scanner optimizes

    * fixed dynamiclinker option which was added at the wrong place

  Revision 1.12  1998/05/23 01:21:32  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 1.11  1998/05/22 12:32:49  peter
    * fixed -L on the commandline, Dos commandline is only 128 bytes

  Revision 1.10  1998/05/11 13:07:58  peter
    + $ifdef NEWPPU for the new ppuformat
    + $define GDB not longer required

    * no findfirst/findnext anymore to remove smartlink *.o files

  Revision 1.9  1998/05/06 08:38:49  pierre
    * better position info with UseTokenInfo
      UseTokenInfo greatly simplified
    + added check for changed tree after first time firstpass
      (if we could remove all the cases were it happen
      we could skip all firstpass if firstpasscount > 1)
      Only with ExtDebug

  Revision 1.8  1998/05/04 20:19:54  peter
    * small fix for go32v2

  Revision 1.7  1998/05/04 17:54:29  peter
    + smartlinking works (only case jumptable left todo)
    * redesign of systems.pas to support assemblers and linkers
    + Unitname is now also in the PPU-file, increased version to 14

  Revision 1.6  1998/05/01 07:43:57  florian
    + basics for rtti implemented
    + switch $m (generate rtti for published sections)

  Revision 1.5  1998/04/29 10:34:06  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

  Revision 1.4  1998/04/27 15:45:20  peter
    + -Xl for smartlink
    + target_info.arext = .a

  Revision 1.3  1998/04/16 10:50:45  daniel
