	* p-lang.h (is_pascal_string_type): Declaration changed,
	new sixth argument of type char ** added.
	* p-lang.c (is_pascal_string_type): Implementation
	changed. Args length_pos, length_size, string_pos, char_size
	can now be NULL. New argument arrayname set to the field
	name of the char array. Return value set to char array
	field index plus one.
	* p-valprint.c (pascal_val_print): Adapt to new declaration of
	is_pascal_string_type function.
