* gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
a ptype to reflect the setting of TARGET_PTR_BIT. Set the TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED. * tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint * printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use it before printing out the hex shape of an address.
