* language.h (struct language_defn): New field c_style_arrays.

	* language.c (unknown_language_defn, auto_language_defn,
	local_language_defn), c-lang.c (c_language_defn, cplus_language_defn,
	asm_language_defn):  Set c_style_arrays to true.
	* m2-lang.c (m2_language_defn), ch-lang.c (chill_language_defn),
	f-lang.c (f_language_defn):  Set c_style_arrays to false.
	* valops.c (value_string):  If c_style_array is not set,
	allocate string in gdb (not inferior) using allocate_value.

	* value.h (COERCE_ARRAY), valops.c (value_addr, value_arg_coerce):
	Only call value_coerce_array if current_language->c_style_arrays.
	* values.c:  Add #include "language.h".  (Needed for COERCE_ARRAY.)

	* valops.c (chill_varying_type):  New predicate.
	* valops.c (value_cast):  Support assigning a fixed string or array
	to a variable string/array structure.

	* valarith.c (value_subscripted_rvalue):  Extra parameter lowerbound.
	Check index>=lowerbound, and then add lowerbound to index here,
	instead of in caller.  Generalize to arbitrary lval_types.
	(value_subscript):  Use enhanced value_subscripted_rvalue if
	c_style_arrays is false (and index is in range).
