	* md4.c (rol): Cast right-shift arg to uint32_t to prevent
	unwanted sign propagation, e.g., on hosts with 64-bit int.
	There still are some problems with reeelly weird theoretical hosts
	(e.g., 33-bit int) but it's not worth worrying about now.
	* sha1.c (rol): Likewise.
	(K1, K2, K3, K4): Remove unnecessary L suffix.
