	* Bug fix: local symbols are now handled properly (see
	           samples/stress{1,2}.mixal)
	* Bug fix: unary - on future refs is handled now (see
	           samples/stress3.mixal).
	* Bug fix: future refs to labels defined with the EQU directive
	           are correctly handled now (see samples/stress4.mixal).
	* Bug fix: configure.in checks for ncurses, needed by readline
