I'm just trying to understand why this type of fix is needed.  How do
I see the relevant errors or warnings?  Is there a tool that claims
there is a problem here? If so, is there a real problem or are we just
trying to avoid dodgy warnings?  :-)

In this particular case the switch covers all the values of the enum,
so ret is always set, hence my lack of understanding.  I always
compile with --picky-developer, so I guess I'm trying to
understand what the O3 developer build is....

No grumpiness or sarcasm... just trying to learn!  :-)

Thanks...

peace & happiness,
martin
