You can do that in C.  Just make the cases the `then' part of if(0)s:

switch (foo)
  {
    case 0: prefix="hi";
    if (0) { case 1: prefix="bye"; }
    if (0) { case 2: prefix="ciao"; }
      strcpy (buffer, "%s Nick", prefix);
      break;
  }

then hope nobody ever has to look at this piece of code again :-)

Yuck :-)
