[PATCH] Fix NPTL forward.c

[Jakub Jelinek]

Hi!

While FORWARD macro has default return value as last argument, FORWARD2
has default action.  With defaction 0 we end up with:
if (someptr == NULL)
  0;
(*someptr) (arguments);
which will segfault if libpthread.so is not loaded.

2004-03-11  Jakub Jelinek  <jakub@redhat.com>

	* forward.c (__pthread_cond_broadcast_2_0,
	__pthread_cond_destroy_2_0, __pthread_cond_init_2_0,
	__pthread_cond_signal_2_0, __pthread_cond_wait_2_0,
	__pthread_cond_timedwait_2_0): Use return 0 as defaction instead of
	0.
