Summary: I have discovered this because i wanted to experiment with building static libomp (with openmp-4.0 support only) for debugging purposes. There are three kinds of problems here: 1. `__kmp_compare_and_store_acq()` simply does not exist. It was added in D47903 by @jlpeyton. I'm guessing `__kmp_atomic_compare_store_acq()` was meant. 2. In `__kmp_is_ticket_lock_initialized()`, `lck->lk.initialized` is `std::atomic<bool>`, while `lck` is `kmp_ticket_lock_t *`. Naturally, they can't be equality-compared. Either, it should return the value read from `lck->lk.initialized`, or do what `__kmp_is_queuing_lock_initialized()` does, compare the passed pointer with the field in the struct pointed by the pointer. I think the latter is correct-er choice here. 3. Tests were not versioned. They assume that `LIBOMP_OMP_VERSION` is at the latest version. This does not touch LIBOMP_OMP_VERSION=30. That is still broken.
