This annoying warning can be silenced by defining the macro mentioned
in the message.

basic_logger::operator= should never be called, it is not used by the
derived classes. It is not clear to me why the compiler generated its
own operator= while there is one already in basic_composite_logger.
Could you post a minimal code sample that triggers this error?
