Currently, 'KDBFLAGS' is an internal variable of kdb, it is combined by 'KDBDEBUG' and state flags. It will be shown only when 'KDBDEBUG' is set, and the user can define an environment variable named 'KDBFLAGS' too. These are puzzling indeed. After communication with Daniel, it seems that 'KDBFLAGS' is a misfeature. So let's replace 'KDBFLAGS' with 'KDBDEBUG' to just show the value we wrote into. After this modification, we can use `md4c1 kdb_flags` instead, to observe the state flags.
