  13 * automatically set __XEN_INTERFACE_VERSION__ to the latest supported
  14 * by the *system* Xen headers which were transitively included.
  15 *
  16 * C files which are part of the internal emulation, and which did not
  17 * include xen_native.h, may need this defined so that the Xen headers
  18 * imported to include/hw/xen/interface/ will expose the appropriate API
  19 * version.
  20 *
  21 * This is why there's a rule that xen_native.h must be included first.
