Subject: Tue Mar 30 08:06:24 1993  Jim Kingdon  (kingdon@cygnus.com)

	* command.c (do_setshow_command): Use %u with var_{u,z}integer.

	* command.{c,h}: New var_type var_integer.
	main.c: Use it for history_size.

	* rs6000-tdep.c, xcoffexec.c, config/rs6000/xm-rs6000.h, breakpoint.c:
	Lint and byte-order fixups.
