Breaks are required as John pointed out in C# even on the default case,
because your code can look like this:

	switch (x){
		default: ...
		case 1:
	}

It is part of the spec, so MCS will do the same thing MS C# does. 
Currently, I do not perform any flow analysis, so you *might* get away
with not putting a final break, but that will change ;-)
