[Nickle]union switch has unreachable default

[Bart Massey]

I've seen this before: ML does it.  Now if you just want to
check a couple of cases, it's a pain.

Although it's better in C/Nickle than ML, actually: you can
just write
  union switch(v) {
  case V1:
    /* handle V1 */
    break;
  default:
    /* only care about V1 */
    break;
  }
to shut the compiler up.  Which would be OK, I guess.

Your call.
