Scott,
I compiled pthreads for 64bit almost out of the box. It works fine so far
with HDF5. Note that I linked statically in order not to mess with any other
library. To make it work, you need to patch pthreads (see below). I also
added the following lines in H5TS.c in H5TS_first_thread_init, but that's
only for static linking
#ifdef _WIN32
#ifdef PTW32_STATIC_LIB
pthread_win32_process_attach_np();
#endif
#endif
