  Initial revision

  Revision 1.33  1998/03/10 23:48:37  florian

      enough, it doesn't run

  Revision 1.32  1998/03/10 16:27:46  pierre
    * better line info in stabs debug
    * symtabletype and lexlevel separated into two fields of tsymtable
    + ifdef MAKELIB for direct library output, not complete
    + ifdef CHAINPROCSYMS for overloaded seach across units, not fully
      working
    + ifdef TESTFUNCRET for setting func result in underfunction, not
      working

  Revision 1.31  1998/03/10 01:17:29  peter
    * all files have the same header
    * messages are fully implemented, EXTDEBUG uses Comment()
    + AG... files for the Assembler generation

  Revision 1.30  1998/03/05 22:43:53  florian
    * some win32 support stuff added

    + Added mac line break

  Revision 1.28  1998/03/02 13:38:51  peter
    + importlib object

    * updated makefile and depend

  Revision 1.25  1998/02/28 00:20:34  florian
    * more changes to get import libs for Win32 working

  Revision 1.24  1998/02/27 22:28:01  florian
    + win_targ unit

  Revision 1.22  1998/02/23 02:55:08  carl
    + added correct extension to AMIGA libext

  Revision 1.21  1998/02/22 23:03:39  peter
    * renamed msource->mainsource and name->unitname
    * optimized filename handling, filename is not seperate anymore with
      path+name+ext, this saves stackspace and a lot of fsplit()'s
    * recompiling of some units in libraries fixed
    * shared libraries are working again
    + $LINKLIB <lib> to support automatic linking to libraries
    + libraries are saved/read from the ppufile, also allows more libraries
      per ppufile

  Revision 1.20  1998/02/18 14:14:44  michael
  * removed entries for dos_targ and lin_targ

  Revision 1.19  1998/02/17 21:21:05  peter
    + Script unit
    + __EXIT is called again to exit a program
    - target_info.link/assembler calls

  Revision 1.18  1998/02/14 01:45:35  peter
    * more fixes
    - pmode target is removed
    - search_as_ld is removed, this is done in the link.pas/assemble.pas
    + findexe() to search for an executable (linker,assembler,binder)

  Revision 1.17  1998/02/13 22:26:45  peter
    * fixed a few SigSegv's
    * INIT$$ was not written for linux!
    * assembling and linking works again for linux and dos
    + assembler object, only attasmi3 supported yet
    * restore pp.pas with AddPath etc.

  Revision 1.16  1998/02/13 10:35:50  daniel
  * Made Motorola version compilable.
  * Fixed optimizer

  Revision 1.15  1998/02/12 17:19:32  florian
    * fixed to get remake3 work, but needs additional fixes (output, I don't like

  Revision 1.14  1998/02/12 11:50:50  daniel
  Yes! Finally! After three retries, my patch!

  Changes:

  Complete rewrite of psub.pas.

  Compiler requires less memory.
  Platform units for each platform.

  Revision 1.11  1998/01/26 16:42:01  daniel
  * Reversed source_ext and pas_ext for OS/2 target. The .pas extension is
  recognized by the Workplace Shell of OS/2, the .pp is not.

  Revision 1.10  1998/01/26 13:35:33  florian
    * adapted to work with TP

  Revision 1.9  1998/01/25 18:45:50  peter
    + Search for as and ld at startup
    + source_info works the same as target_info
    + externlink allows only external linking

  Revision 1.8  1998/01/22 08:57:55  peter
    + added target_info.pasext and target_info.libext

  Revision 1.7  1998/01/09 19:44:09  carl
    * labels for mac68k target now use the MPW correct syntax

  Revision 1.6  1997/12/12 13:28:42  florian
  + version 0.99.0
  * all WASM options changed into MASM
  + -O2 for Pentium II optimizations
