  $Log$
  Revision 1.48  2002-07-04 20:40:09  florian
    + some x86-64 support added

  Revision 1.47  2002/07/01 16:29:05  peter
    * sLineBreak changed to normal constant like Kylix

  Revision 1.46  2002/06/02 10:49:30  marco
   * Renamefest supports_double for FreeBSD too

  Revision 1.45  2002/04/21 15:51:51  carl
  * StackError is now a typed constant
  + $S can be used under unix

  Revision 1.44  2002/04/12 17:35:24  carl
  - removed unused variable

  Revision 1.43  2002/01/25 17:41:05  peter
    * moved array types to objpas unit

  Revision 1.42  2002/01/25 17:39:35  peter
    * array types added

  Revision 1.41  2002/01/24 18:27:06  peter
    * lowercase() overloaded

  Revision 1.40  2002/01/24 12:33:53  jonas
    * adapted ranges of native types to int64 (e.g. high cardinal is no
      longer longint($ffffffff), but just $fffffff in psystem)
    * small additional fix in 64bit rangecheck code generation for 32 bit
      processors
    * adaption of ranges required the matching talgorithm used for selecting
      which overloaded procedure to call to be adapted. It should now always
      select the closest match for ordinal parameters.
    + inttostr(qword) in sysstr.inc/sysstrh.inc
    + abs(int64), sqr(int64), sqr(qword) in systemh.inc/generic.inc (previous
      fixes were required to be able to add them)
    * is_in_limit() moved from ncal to types unit, should always be used
      instead of direct comparisons of low/high values of orddefs because
      qword is a special case

  Revision 1.39  2001/11/14 22:59:11  michael
  + Initial variant support

  Revision 1.38  2001/11/07 14:59:20  michael
  + Moved PathDelim,DriveDelim,PathSep to sysutilh

  Revision 1.37  2001/11/07 13:52:37  michael
  + Added PathDelim,DriveDelim,PathSep

  Revision 1.36  2001/10/09 02:32:51  carl
  * bugfix #1639 (IsMultiThread varialbe setting)

  Revision 1.35  2001/08/19 21:02:01  florian
    * fixed and added a lot of stuff to get the Jedi DX8 headers
      compiled

  Revision 1.34  2001/08/01 18:01:20  peter
    * WChar fix to compile also with 1.0.x

  Revision 1.33  2001/08/01 15:00:11  jonas
    + "compproc" helpers
    * renamed several helpers so that their name is the same as their
      "public alias", which should facilitate the conversion of processor
      specific code in the code generator to processor independent code
    * some small fixes to the val_ansistring and val_widestring helpers
      (always immediately exit if the source string is longer than 255
       chars)
    * fixed fpc_dynarray_high and fpc_dynarray_length if the dynarray is
      still nil (used to crash, now return resp -1 and 0)

  Revision 1.32  2001/07/31 08:57:22  marco
   * Either I did something wrong, or Peter's merge killed wchar decl. Fixed.

  Revision 1.31  2001/07/30 21:38:55  peter
    * m68k updates merged

  Revision 1.29  2001/07/29 13:49:15  peter
    * m68k updates merged

  Revision 1.28  2001/07/15 11:57:16  peter
    * merged m68k updates

    - removed all ifdef cardinalmulfix code

  Revision 1.14  2000/12/08 14:04:43  jonas
    + added pos(char,ansistring), because there is also a pos(char,shortstring)
      and without the ansistring version, the shortstring version is always
      called when calling pos(char,pchar), even when using $h+ (because the
      first parameter matches exactly) (merged)

  Revision 1.13  2000/12/07 17:19:47  jonas
    * new constant handling: from now on, hex constants >$7fffffff are
      parsed as unsigned constants (otherwise, $80000000 got sign extended
      and became $ffffffff80000000), all constants in the longint range
      become longints, all constants >$7fffffff and <=cardinal($ffffffff)
      are cardinals and the rest are int64's.
    * added lots of longint typecast to prevent range check errors in the
      compiler and rtl
    * type casts of symbolic ordinal constants are now preserved
    * fixed bug where the original resulttype wasn't restored correctly
      after doing a 64bit rangecheck
