It ERANGE's only on Inf, not underflow?  I would prefer:

    else if (errno == ERANGE && !isinf(result))

because the sign computation isn't 100%, think pow(-1e300, 2) == Inf,
not -Inf.  But of course, that is going throw an error anyway, so either
we care about the sign of the Inf and try to get it right using isinf(),
or we just ignore it and use +Inf always.
