2006-07-28 Ulrich Drepper <drepper@redhat.com>
* sysdeps/unix/sysv/linux/kernel-features.h: Define
__ASSUME_FUTEX_LOCK_PI.
* include/time.h: Declare __nanosleep_nocancel.
* include/unistd.h: Declare __pause_nocancel.
* dlfcn/Makefile (LDLIBS-bug-atexit3-lib.so): Use this instead of
LDFLAGS. Add -lgcc_eh and libc_nonshared (again) to make sure we
get the __stack_chk_fail_local definition when it's needed.
