It looks like you have the "treat warnings as errors" compiler flag
switched on.  I admire the purity of those that think this is appropriate
but we're not there yet.  There are very few warnings issued from the
interpreter, one form the cogit, but many from plugins.  And that warning
form the cogit is IMO fascist, and I'm not interested in buckling under ;-)
