Hmm, I'm not sure that enable-threadsafe has any impact anymore, in 2000
we removed some of the thread/non thread options - and looking closely I
think that the removal wasn't as accurate as it could be. Anyway, I
suggest not passing either thread option to cygwin.

The overhead shouldn't be that significant, but try it without and see
for yourself :}.
