  Modified files:
    lib/libc/ia64        _fpmath.h 
  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 anyway.
  - Add an XXX comment for the big endian case.
