{
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

* some fixes of Peter applied:
ofs problem, profiler support
Revision 1.39 1998/03/10 15:20:30 carl
* bugfix of spelling mistake
* make it compile under TP with overlays
Revision 1.38 1998/03/10 13:23:00 florian
* small win32 problems fixed
Revision 1.37 1998/03/10 01:17:24 peter
* all files have the same header
* messages are fully implemented, EXTDEBUG uses Comment()
+ AG... files for the Assembler generation
Revision 1.36 1998/03/06 00:52:46 peter
* replaced all old messages from errore.msg, only ExtDebug and some
Comment() calls are left
* fixed options.pas
Revision 1.35 1998/03/05 02:44:16 peter
* options cleanup and use of .msg file
Revision 1.34 1998/03/04 17:33:52 michael
+ Changed ifdef FPK to ifdef FPC
Revision 1.33 1998/03/02 23:08:42 florian
* the concatcopy bug removed (solves problems when compilg sysatari!)
Revision 1.32 1998/03/02 16:02:04 peter
* new style messages for pp.pas
* cleanup of pp.pas
Revision 1.31 1998/03/02 13:38:49 peter
+ importlib object
* doesn't crash on a systemunit anymore
* updated makefile and depend
Revision 1.30 1998/03/02 01:49:05 peter
* renamed target_DOS to target_GO32V1
+ new verbose system, merged old errors and verbose units into one new
verbose.pas, so errors.pas is obsolete
Revision 1.29 1998/02/25 14:31:28 jonas
* added $d- for TP compiling (disable strict var checking) and removed a duplicate $M statement
Revision 1.28 1998/02/22 23:03:29 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

- File Searching mechanism is uniform for all files.
- Include path is working now !!
All fixes by Peter Vreman. Tested with remake3 target.
Revision 1.11 1998/01/07 00:17:04 michael
