How do you do this code:

switch (count % 8)  /* count > 0 assumed */
{
   case 0:        do {  *to++ = *from++;
   case 7:              *to++ = *from++;
   case 6:              *to++ = *from++;
   case 5:              *to++ = *from++;
   case 4:              *to++ = *from++;
   case 3:              *to++ = *from++;
   case 2:              *to++ = *from++;
   case 1:              *to++ = *from++;
                     } while ((count -= 8) > 0);
}
