$Log$
Revision 1.7 1998-08-31 12:26:27 peter
* m68k and palmos updates from surebugfixes
Revision 1.6 1998/08/21 14:08:44 pierre
+ TEST_FUNCRET now default (old code removed)
works also for m68k (at least compiles)
Revision 1.5 1998/06/04 23:51:45 peter
* m68k compiles
+ .def file creation moved to gendef.pas so it could also be used
for win32
Revision 1.4 1998/05/23 01:21:10 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 1.3 1998/05/11 13:07:54 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 1.2 1998/04/29 10:33:54 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
