gaur does not seem happy with this. I get the impression that pow(1,
NaN) and pow(NaN, 0) on that machine must be returning NaN and setting
errno to EDOM, and now that we're only using that code path when both
are are non-NaN we no longer hit the special case which does result =
1;
I wonder if it's better just to hard code these two cases before even
calling the pow() function.
