+/* 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.
+
+   When using the Linux futex primitive, non-recursive locks require
+   only one int.  Recursive locks require we identify the owning task
+   and so require one int and a pointer.  */
