Well, apparently the glibc maintainer doesn't agree with me (big
surprise), so it seems that proj should be made so that it can handle
errno getting set to ERANGE. I'm not sure what the best way would be.
I'd be tempted for now just to set errno to 0 after calling atof, but
that is not very good form.
