Revision 1.1.1.1 1998/03/25 11:18:12 root
* Restored version
Revision 1.5 1998/03/10 01:17:15 peter
* all files have the same header
* messages are fully implemented, EXTDEBUG uses Comment()
+ AG... files for the Assembler generation
Revision 1.4 1998/03/02 01:48:07 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verbose.pas, so errors.pas is obsolete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 1.3 1998/02/13 10:34:37 daniel
* Made Motorola version compilable.
* Fixed optimizer
Revision 1.2 1998/01/27 23:34:35 peter
+ SIGINT capture with exit. It works for linux and go32v2 (last one
not 100% yet)
