As the kbuild bot points out, this does not work since the existence of a typedef cannot be checked with #ifdef. I'm not really sure what problem you're trying to solve. A user space program making use of this interface gets the domid_t and xen_pfn_t etc typedefs from the headers provided as part of the libxenctrl library.
