Well, ISO C doesn't define complex integers at all. But it's deliberate (see DR#206) that _Complex float doesn't promote to _Complex double in variable arguments. And there is nothing in ISO C to stop _Complex float being passed in variable arguments. For all these types including the complex integer ones: given that the front end doesn't promote them, they should be usable in variable arguments. -- Joseph S. Myers jos...@codesourcery.com
