case value 'value' already used.

A switch statement uses the same case value more than once.

The following sample generates C2196:

// C2196.cpp
int main() {
   int i = 0;
   switch( i ) {
   case 0:
      break;
   case 0:   // C2196
   // try the following line instead
   // case 1:
      break;
   }
}
