BUG with bits in integer variable

unsigned int bdata my_int;
sbit bit15 = my_int ^ 15;
sbit bit7 = my_int ^ 7;

void main()
{
  my_int = 0x8000;

  if(bit15)
  {
    // Here we shall not appear,as compiller
    // will be erroneous to check 7-bit of
    // a variable my_int instead of 15-bit
    // (as this variable place in memory in
    // little endian order)
    // ...
  }

  if(bit7)
  {
    // oops! we here!
    // ...
  }
}
