It is a workaround, and I can't think of a better one. The issue is that the
"friend class ClientProvider;" should apply to "ClientProvider::Impl" as well.
Apparently this isn't the case for gcc 3.5.
Exposing this type isn't a practical issue as there isn't much which can be done with it.
The definition is hidden and the methods which use it remain private.

It's the situation where

required an accessible copy ctor in older iterations of the c++ standard,
although I hope it would never actually be called.
