re PR boehm-gc/34544 (pthread_default_stacksize_np failed.) 

PR boehm-gc/34544
	* gthr-posix.h (__gthread_start): Delete.
	(__gthread_active_init): Use pthread_default_stacksize_np instead of
	pthread_create to determine if hpux pthreads are active.
	* gthr-posix95.h (__gthread_start): Delete.
	(__gthread_active_init): Likewise use pthread_default_stacksize_np.
