	* function.c (allocate_struct_function): Do not set
	current_function_returns_pointer.
	* function.h (struct var_refs_queue): Remove.
	(struct simple_obstack_stack): Likewise.
	(struct function): Remove fixup_var_refs_queue member.
	Remove returns_pointer flag.
	(current_function_returns_pointer): Remove define.
