g++ 2.96 -W issues bogus warning for conditional expression with enum and unsigned

Each of the warning flags has explanation what warnings it
produces. For -W, there is a list of specific warnings that it
triggers. I think this list should be complete. If nobody volunteers
to systemaically check whether all extra warnings are explained there,
we should at least add documentation whenever we detect such a case.
