	* eval.c (language.h): Include.
	* eval.c (evaluate_subexp_with_coercion):  Only coerce arrays
	to pointer types when the current language is C.  It loses for
	other languages when the lower index bound is nonzero.
	* valarith.c (value_subscript):  Take array lower bounds into
	account when performing subscripting operations.
	* valops.c (value_coerce_array):  Add comment describing why
	arrays with nonzero lower bounds are dealt with in value_subscript,
	rather than in value_coerce_array.
