2002-06-18  Vladimir Makarov  <vmakarov@redhat.com>

	* rtl.def (DEFINE_AUTOMATON): Add description of new options
	`time' and `v'.  Fix incorrect description of option `w'.

	* doc/md.texi: Ditto.

	* genautomata.c (TIME_OPTION, V_OPTION): New macros.
	(gen_automata_option): Process the new options.
	(transform_2, transform_3): Initialize some variables.
	(initiate_automaton_gen): Use the new macros.
