Yes I realise that - what I don't realise is _why_ that symbol was
defined when you were building! Cygwin doesn't define it, and python
shouldn't define it.

PTH doesn't integrate in with cygwin behind the scenes, so things like
pthread_atfork won't work, and shared memory access to mutex's will be
broken as well. Or did you mean that their test suite works? 

Also are you talking the redhat hosted GNU portable threads for win32?
Or a more general library based threads implementation (because these
are often userland and as such not actually concurrent.

Perhaps a url for the one you are talking about?
