Yes, it's well defined, but what it's defined to do is bad.
For a formal treatment of the above statement, I refer you to my article
<16039@haddock.ima.isc.com>, posted to comp.lang.misc (also .c and .ada) with
this same title. I haven't seen any rebuttals yet.

Yeah. I wish C had this feature, instead of simulating it with fallthrough.

I don't know about the person you were addressing, but I think I've had
sufficient experience with it. I certainly question its usefulness in
comparison to something reasonable, like the language I described in my other
article.
In fact, even if you insist that the comparison must be between C and
plain-C-without-break-switch, I think I'd still go for the latter. I believe
the benefit of not requiring an overloaded keyword to do a break-switch
exceeds the cost of having to use a goto to merge related cases.
