Confirmed with current sources.  The patch helps with some cases (and since
it's basically making the same changes to three files, might be just small
enough to use without a copyright assignment) but you still get underflow in
cases where the result should have a subnormal imaginary part (e.g. an argument
of 710 + i).  The same issues will apply to ctan.
