In the spec it's only stated fmin/fmax satisfies minNum/maxNum in IEEE 754-2008. However IEEE 754-2008 has left the result of minNum(0.0, -0.0) and maxNum(0.0, -0.0) "either 0.0 or -0.0", but Glibc fminimum/fmaximum implementations are already using fmin/fmax and assuming them treating -0.0 as is smaller than 0.0. Thus if an implementation changes the edge-case behavior (note that the change won't violate the currect spec text), Glibc will be blown up.

Similar to #38.
