/* This header is used during the build process to find the size and

   alignment of the public OpenMP locks, so that we can export data

   structures without polluting the namespace.

   In this default POSIX implementation, we used to map the two locks to the

   same PTHREADS primitive, but for OpenMP 3.0 sem_t needs to be used

   instead, as pthread_mutex_unlock should not be called by different

   thread than the one that called pthread_mutex_lock.  */
