- Revision 1.24 1998/08/11 21:39:08 peter
- * splitted default_extended from support_extended
-
- Revision 1.23 1998/08/11 00:05:27 peter
- * $ifdef ver0_99_5 updates
-
- Revision 1.22 1998/08/08 12:28:14 florian
- * a lot small fixes to the extended data type work
-
- Revision 1.21 1998/07/30 13:26:17 michael
- + Added support for ErrorProc variable. All internal functions are required
- to call HandleError instead of runerror from now on.
- This is necessary for exception support.
-
- Revision 1.20 1998/07/28 20:37:47 michael
- + added setjmp/longjmp and exception support
-
- Revision 1.19 1998/07/20 23:36:57 michael
- changes for ansistrings
-
- Revision 1.18 1998/07/18 17:14:24 florian
- * strlenint type implemented
-
- Revision 1.17 1998/07/10 11:02:39 peter
- * support_fixed, becuase fixed is not 100% yet for the m68k
-
- Revision 1.16 1998/07/02 12:13:18 carl
- * No SINGLE type for m68k or other non-intel processors!
-
- Revision 1.15 1998/07/01 14:43:46 carl
- - max_frame_dump reduced to 8, 20 is too much!
-
- Revision 1.14 1998/06/25 14:04:26 peter
- + internal inc/dec
-
- Revision 1.13 1998/06/25 09:44:21 daniel
- + RTLLITE directive to compile minimal RTL.
-
- Revision 1.12 1998/06/15 15:16:27 daniel
-
- * RTLLITE conditional added to produce smaller RTL
-
- Revision 1.11 1998/06/08 12:38:23 michael
- Implemented rtti, inserted ansistrings again
-
- Revision 1.10 1998/06/04 23:46:02 peter
- * comp,extended are only i386 added support_comp,support_extended
-
- Revision 1.9 1998/06/04 08:26:03 pierre
- * boolean internal definition again (needed to compile
- older RTL's)
-
- Revision 1.8 1998/06/03 23:39:53 peter
- + boolean=bytebool
-
- Revision 1.7 1998/05/22 12:34:11 peter
- * fixed the optimizes of daniel
-
- Revision 1.6 1998/05/21 19:31:00 peter
- * objects compiles for linux
- + assign(pchar), assign(char), rename(pchar), rename(char)
- * fixed read_text_as_array
- + read_text_as_pchar which was not yet in the rtl
-
- Revision 1.5 1998/05/12 10:42:45 peter
- * moved getopts to inc/, all supported OS's need argc,argv exported
- + strpas, strlen are now exported in the systemunit
- * removed logs
- * removed $ifdef ver_above
-
- Revision 1.4 1998/04/16 12:30:47 peter
- + inc(pchar), dec(pchar), incc(pchar,a),dec(pchar,a)
- }
