That's your choice, and it depends on your application. 
Range based exception handling is preferred on many targets because
there's no inline cost when exceptions aren't thrown. On some
machines other choices are preferable, and we simply don't have range
based exception handling for other targets.
So, whatever floats your boat: with gcj we give you the choice.
Andrew.
