That was quick. I just pushed that out to github and hadn't announced it
anywhere. I didn't realize that a new branch on my tree would be
automatically tested, but I'm glad this got caught!

It looks like I need to compile for a 32-bit platform before sending
this out to a larger audience.

Thanks!!
