{
possible compiler switches (* marks a currently required switch):
-----------------------------------------------------------------
USE_RHIDE generates errors and warning in an format recognized
by rhide
TP to compile the compiler with Turbo or Borland Pascal
GDB* support of the GNU Debugger
I386 generate a compiler for the Intel i386+
M68K generate a compiler for the M68000
MULLER release special debug code of Pierre Muller
(needs some extra units)
USEOVERLAY compiles a TP version which uses overlays
EXTDEBUG some extra debug code is executed
SUPPORT_MMX only i386: releases the compiler switch
MMX which allows the compiler to generate
MMX instructions
EXTERN_MSG Don't compile the msgfiles in the compiler, always
use external messagefiles
NOAG386INT no Intel Assembler output
NOAG386NSM no NASM output
-----------------------------------------------------------------
Required switches for a i386 compiler be compiled by Free Pascal Compiler:
GDB;I386
Required switches for a i386 compiler be compiled by Turbo Pascal:
GDB;I386;TP
Required switches for a 68000 compiler be compiled by Turbo Pascal:
GDB;M68k;TP

$Log$
Revision 1.21 1998-07-18 17:11:12 florian

* released NEWINPUT
Revision 1.19 1998/07/07 11:20:04 peter
+ NEWINPUT for a better inputfile and scanner object
Revision 1.18 1998/06/24 14:06:33 peter

+ UseTokenInfo now default
* unit in interface uses and implementation uses gives error now
* only one error for unknown symbol (uses lastsymknown boolean)

+ first inlined procedures and function work
(warning there might be allowed cases were the result is still wrong !!)
* UseBrower updated gives a global list of all position of all used symbols
with switch -gb
Revision 1.10 1998/05/12 10:47:00 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 1.9 1998/05/11 13:07:56 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 1.8 1998/05/08 09:21:57 michael
+ Librarysearchpath is now a linker object field;
Revision 1.7 1998/05/04 17:54:28 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 1998/04/29 13:40:23 peter
+ heapblocks:=true
Revision 1.5 1998/04/29 10:33:59 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 1.3 1998/04/21 10:16:48 peter
* patches from strasbourg
* objects is not used anymore in the fpc compiled version
Revision 1.2 1998/04/07 13:19:47 pierre
* bugfixes for reset_gdb_info
in MEM parsing for go32v2
better external symbol creation
support for rhgdb.exe (lowercase file names)
