Update.
2002-04-08  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/pthread/timer_getoverr.c: Return real overrun.
	* sysdeps/pthread/posix-timer.h (struct timer_node): Add overrun_count.
	* sysdeps/pthread/timer_routines.c (thread_func): Schedule next timeout
	based on previous one and not on current time.  Count overruns.
	Patch by Eric F. Sorton <eric@cctcorp.com>.

	* sysdeps/unix/sysv/linux/bits/local_lim.h: Add DELAYTIMER_MAX.

	(FLOATING_STACKS, ARCH_STACK_MAX_SIZE): Defined.
