It also happens on the mainline (20030717) but I think this code is invalid as the error 
meesages, it is not a lvalue.
I think the correct thing to do is to correct the code:
void f (struct id *dev, unsigned int size, int idx)
{
  int t;
  __asm__ __volatile__
    ("" : "=r" (t));
  if(size == 4u)
    dev->u.kc32[idx] = t;
  else
    dev->u.kc16[idx] = t;
  return;
}

Which produces the same results on 2.95.3 as previous code and actually compiles on 
3.3 and the mainline.
