Subject: PR c++/5645 gcc warns that pure virtual class not explicitly initialized

:ADDPATCH c++:

The patch below avoids this warning by checking for nearly emptiness.
I am not sure that this is the correct approach for 100% cases, since
I ignore all specific cases that should be warned and that shouldn't.

Bootstrapped and regression tested.

OK to commit?

Cheers,

Manuel.
