  Log:
  Define LDBL_NBIT to be a mask indicating the position of the integer
  bit in a long double.  For architectures that don't have such a bit,
  LDBL_NBIT is 0.  This makes it possible to say `mantissa & ~LDBL_NBIT'
  in places that previously used an #ifdef to select the right expression.
  The optimizer should dispense with the extra arithmetic when LDBL_NBIT
  is 0.
