I've updated the source (and Mac build) to include the changes provided by sesef. No other changes were made. I'll let rebirther build the Win32 and Win64 exes as I still can get them to build and run correctly.

Make sure that you test ranges with known special instances.

Also, please test some WallSunSun ranges (-TWallSunSun). They are a little slower, but the software can verify that the code on the GPU was executed correctly whereas it can't do that for Wieferich.

I hope to test the PRPNet changes this weekend so that we can start using wwwwcl in production next week.
