Still fighting 64-bit

[Yuri Sadykov <sadykov@gmail.com>]

Guys,

I still unclear of 64-bit support of current pthread inmlementation on Windows.
I use Visual Studio 2008 to produce native 64-bit executable.
I got pthread sources from top of cvs repository and build the
library. I read somewhere that static lib is not good for some
reasons, so I build DLL. But I have problem with
pthread_cond_destroy(), program crashes on that call.
pthread_cond_destroy() calls pthread_mutex_trylock(), which tries to
call by zero pointer. ptw32_interlocked_compare_exchange should point
to actual function but it is NULL pointer.

  if (0 == (LONG) PTW32_INTERLOCKED_COMPARE_EXCHANGE (
		     (PTW32_INTERLOCKED_LPLONG) &mx->lock_idx,
		     (PTW32_INTERLOCKED_LONG) 1,
		     (PTW32_INTERLOCKED_LONG) 0))

Any thoughts? Did I miss some important build steps, like special
defines or something, or maybe there are patches to current CVS trunk?

Best,
