* stor-layout.c (pending_sizes): Change the type to

	VEC(tree,gc) *.
	(get_pending_sizes, put_pending_size, put_pending_sizes):
	Update the uses of pending_sizes.
	* c-decl.c (store_parm_decls): Likewise.
	* c-tree.h (struct c_arg_info): Likewise.
	* tree.h: Update the prototype for get_pending_sizes and
	put_pending_sizes.
