12  * __XEN_TOOLS__ here before any Xen headers are included. Otherwise, if
13  * the Xen toolstack library headers are later included, they will find
14  * some of the "internal" definitions missing and the build will fail. In
15  * later commits, we'll end up with a rule that the native libraries have
16  * to be included first, which will ensure that the libraries get the
17  * version of Xen libraries that they expect.
