	PR middle-end/17909
	* builtins.c (fold_builtin_next_arg): Export and return true
	when there is a warning or an error.
	(expand_builtin_va_start): When fold_builtin_next_arg returns true,
	return const0_rtx.
	(expand_builtin): Likewise.
	* gimplify.c (gimplify_call_expr): Error out if there is not
	enough arguments to va_start. Call fold_builtin_next_arg also
	on the second argument.
	* tree.h (fold_builtin_next_arg): Prototype.
