Update.
2002-12-13 Ulrich Drepper <drepper@redhat.com> * misc/syslog.c (log_cleanup): Don't use parameter in __libc_lock_unlock call, use syslog_lock directly. Adjust callers to pass NULL instead of a pointer to syslog_lock.

-/* This function is responsible for calling all registered cleanup

- fact that we have to handle to cancellation handler registration
- methods: exceptions using try/finally and setjmp.

- The setjmp method is always available. The user might compile some
- code which uses this method because no modern compiler is
- available. So we have to handle these first since we cannot call
- the cleanup handlers if the stack frames are gone. At the same
- time this opens a hole for the register exception handler blocks
- since now they might be in danger of using an overwritten stack
- frame. The advise is to only use new or only old style cancellation
- handling. */
