     * There are two expected ways of including this header.

     * 1) The "default" case (expected from tools etc).
     *
     * Simply #include <public/errno.h>
     *
     * In this circumstance, normal header guards apply and the includer shall get
     * an enumeration in the XEN_xxx namespace, appropriate for C or assembly.
     *
     * 2) The special case where the includer provides a XEN_ERRNO() in scope.
     *
     * In this case, no inclusion guards apply and the caller is responsible for
     * their XEN_ERRNO() being appropriate in the included context.  The header
     * will unilaterally #undef XEN_ERRNO().
