Short of writing our own compiler I don't see how to fix this behavior either. I have run into it before and I fixed it "in the documentation". That is, I warned students about the problems of taking roots of negative numbers and how it was actually done on computers using logs. It was a calculus class, so they were actually reasonably interested in how computers calculated such things.
My guess is that a pocket calculator wouldn't do any better on this answer, but I haven't tried it recently.
