1/* This header is used during the build process to find the size and
2   alignment of the public OpenMP locks, so that we can export data
3   structures without polluting the namespace.

5   In this default POSIX implementation, we used to map the two locks to the
6   same PTHREADS primitive, but for OpenMP 3.0 sem_t needs to be used
7   instead, as pthread_mutex_unlock should not be called by different
8   thread than the one that called pthread_mutex_lock.  */
