My first question is that the ./configure states that
--disable-threads is "enabled by default". Is that a typo?

Assuming that isn't an error, then would it be possible to have
--disable-threads also disable the running of the threads test in make
check? Or is running the threads test still desirable even though
--disable-threads is set in the ./configure?

Thanks,
Dave
