Use <code>-fpermissive</code> to allow the old, non-conforming behaviour.
</li>
+ <li>G++ no longer allows objects of const-qualified type to be default
+ initialized unless the type has a user-declared default constructor.
+ Code that fails to compile can be fixed by providing an initializer e.g.
+ <pre>
+ struct A { A(); };
+ struct B : A { };
+ const B b = B();
+ </pre>
