The only timespec declaration on Win32 is the one in pthread.h, that's
why I or'ed  SCM_I_GSC_USE_PTHREAD_THREADS.
scm's own timespec declaration is considered "incompatible" for some reason.

OK, makes sense.

Pthreads-win32 defines pthread_t as struct.

pthread_attr_getstack() exists, but pthread_getattr_np() doesn't.
This is just to get the #define HAVE_GET_... and the definition of
get_thread_stack_base().
