Hi,
I have a compilation error with a virtual function inside a virtual base 
class.
For example, I just add a function f() inside the unit test : 
"test_diamond.cpp".

class base {
...
    virtual void f() =0;
...
};

class derived1 {
...
    virtual void f(){}
...
};

gcc 4.3, returns me an error:
error: no unique final overrider for `virtual void base::f()' in 
`boost::detail::is_virtual_base_of_impl<derived1, final, mpl_::bool_< 
true> >::X'

The same code works properly with msvc 2005.

Best regards,
Fabien Castan
