C99, Section 7.15, simply says that it "is an object type suitable for holding information needed by the macros va_start, va_end, and va_copy". So clearly not guaranteed to be mixable with pointers. And not prohibited from being mixable either, for that matter. And, nit-pickingly, NULL might be a valid value representing some sequence of arguments if the two are mixable. M.
