  Log:
  MFC fpu_explode.c 1.6 and fpu_qp.c 1.6:
    Fix long (and long long) to long double, unsigned to long double and unsigned
    long (and unsigned long long) to long double conversions.
    - Add a parameter that specifies the position of the sign bit to the _QP_TTOQ
      macro, previously it always looked at bit 31.  Pass a negative number to
      disable sign inspection for unsigned types.  This fixes _Qp_xtoq(),
      _Qp_uitoq() and _Qp_uxtoq().
    - In the functions __fpu_itof() and __fpu_xtof(), look at the sign bit to
      decide whether we're doing a conversion from an unsigned type.  If so, don't
      negate the mantissa if the integer exceeds the biggest signed number.
