Update.

2002-12-30  Jakub Jelinek  <jakub@redhat.com>

	* forward.c (FORWARD2): Renamed from FORWARD3.  Remove unused export
	argument.
	(pthread_attr_init_2_0, pthread_attr_init_2_1): Use FORWARD macro.
	(pthread_exit): Use strong_alias to avoid warnings.
	* pthreadP.h (struct pthread_functions): Rename ptr_pthread_exit
	and ptr_pthread_attr_init_2_* to ptr___pthread_exit and
	ptr___pthread_attr_init_2_*.
	* init.c (pthread_functions): Adjust.
