I checked this in with a small addition. While testing I found that Cygwin's pthread_mutex_unlock returned EINVAL if the mutex is of the PTHREAD_MUTEX_ERRORCHECK type and the mutex wasn't owned by any thread (as in your STC), Linux returns EPERM in this case. I fixed that. Thanks, Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
