EnterCriticalSection (&ptw32_cond_list_lock) on pthreads-w32-2-6-0-release

[Nigel Horne]

What are the circumstances under which VS2005 gives an
access violation whenever
	EnterCriticalSection(&ptw32_cond_list_lock);
is called in any of the pthread functions?

Since ptw32_cond_list_lock is an internal variable, I can't
see that I supposed to initialise it, yet nothing works
because of this EnterCriticalSection problem, e.g.
	pthread_cond_init
will fail.
