  $Log$
  Revision 1.12  1998-07-07 11:20:19  peter
    + NEWINPUT for a better inputfile and scanner object

  Revision 1.11  1998/06/19 15:40:00  peter
    * bp7 fix

  Revision 1.10  1998/06/16 11:32:19  peter
    * small cosmetic fixes

  Revision 1.9  1998/05/23 01:21:33  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 1.8  1998/05/21 19:33:38  peter
    + better procedure directive handling and only one table

  Revision 1.7  1998/05/12 10:47:01  peter
    * moved printstatus to verb_def
    + V_Normal which is between V_Error and V_Warning and doesn't have a
      prefix like error: warning: and is included in V_Default
    * fixed some messages
    * first time parameter scan is only for -v and -T
    - removed old style messages

  Revision 1.6  1998/05/11 13:07:58  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 1.5  1998/04/30 15:59:43  pierre
    * GDB works again better :
      correct type info in one pass
    + UseTokenInfo for better source position
    * fixed one remaining bug in scanner for line counts
    * several little fixes

  Revision 1.4  1998/04/29 10:34:09  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
