  Modified files:
    lib/libc/sparc64/fpu fpu_explode.c fpu_qp.c 
  Log:
  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.
