It's equivalent to this:
const int i;
which is pretty much certain to be an error and the compiler is doing
you a favour if it rejects it.
The ISO standard says (in 8.5 [dcl.init] paragraph 9):
If no initializer is specified for an object, and the object is of
(possibly cv-qualified) non-POD class type (or array thereof), the
object shall be default-initialized; if the object is of
const-qualified type, the underlying class type shall have a
user-declared default constructor.
The second half of that paragraph applies to A2.
