Actually, in an X3J11-conforming compiler, you get an error message.
You can't default both type and storage class in X3J11 C.

It's not useful, but there is probably old code somewhere that declares
some local int variables with "auto i;" instead of "int i;".  Sigh.

It is explicitly illegal in X3J11 C.

Nothing.  It's no longer part of the language.
