I think I have found the issue (a missing call to add pthread library
for linking) but I need to test on Linux. I'll reply shortly after
testing.

I've pushed a commit.  I have no idea why it would link to pthread
here on MinGW and Debian without the call, but it seems to work fine
either way.  I'm guessing maybe different versions of gcc deal with
pthread differently?  Anyways, could you pull the latest John and give
it a try now?
