>Description:
Currently -Wswitch requires that a switch not
have a default case.  This isn't always the most
useful thing though.  In my situation, I have a 
bytecode interpreter.  I'd like to use -Wswitch to
ensure that I haven't left out a bytecode.  But
I'd also like to have a default case so that 
erroneous bytecodes are caught.
I think -Wswitch should be augmented to allow this case.
Perhaps a new -Wswitch-default flag could be added.
