	* parse.c (follow_types):  Given (TYPE[]) (i.e. with no length),
	create a 0-length array type, and set BOUND_CANNOT_BE_DETERMINED.
	* valops.c (value_cast):  If a cast like (TYPE[])VALUE (i.e. array
	of unknown length) use sizeof(VALUE)/sizeof(TYPE) as the length.
	* c-typeprint.c (c_type_print_varspec_suffix):  If array length
	is 0, print it, but not if upper_bound is BOUND_CANNOT_BE_DETERMINED.
