gcc has this problem as well. Although, it will let you have an expression using
only constants like

case 'A' + ('B'<<8):

but not

case *((uint16_t *)"AB"):

A gcc example:

#include <stdio.h>

int main()
{
  unsigned int xxx = 0x3456;

  switch(0x34)
  {
  case ((int)(xxx >> 16)):
    printf("Shift\n");
    break;
  default:
    printf("No shift\n");
    break;
  }

  return(0);
}
