{
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
-----------------------------------------------------------------
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 1.7 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)
