As I wrote in those bugs and Kriang has too.  That we were friending 
the wrong class
pre 4.0.0, now in 4.0.0 we declare a class which should not be there.
In 4.1.0 we do every thing correctly.  Even if the patches in the 
mainline were
backported the code in those projects still have to change to get the 
behavior which
they were expecting.

Thanks,
