+Assuming uxMaxCount > 0, uxInitialCount <= uxMaxCount and the reference
+to the storage area is not null,
+this harness proves the memory saftey of QueueCreateCountingSemphoreStatic.
+
+This proof is a work-in-progress.  Proof assumptions are described in
+the harness.  The proof also assumes the following functions are
+memory safe and have no side effects relevant to the memory safety of
+this function:
+
+* vPortEnterCritical
+* vPortExitCritical
