__XEN__ causes the following compilation error:

In file included from include2/asm/page.h:236,
                 from include2/asm/ptrace.h:234,
                 from include2/asm/processor.h:19,
                 from include2/asm/thread_info.h:11,
                 from /linux-2.6.18-xen.hg/include/linux/thread_info.h:21,
                 from /linux-2.6.18-xen.hg/include/linux/preempt.h:9,
                 from /linux-2.6.18-xen.hg/include/linux/spinlock.h:49,
                 from /linux-2.6.18-xen.hg/include/linux/mmzone.h:7,
                 from /linux-2.6.18-xen.hg/include/linux/gfp.h:4,
                 from /linux-2.6.18-xen.hg/arch/ia64/xen/xcom_privcmd.c:23:
include2/asm/hypervisor.h:63: error: expected '=', ',', ';', 'asm' or 
'__attribute__' before '*' token

The line of the problem is as follows:
  extern shared_info_t *HYPERVISOR_shared_info;

The identifier `shared_info_t' is defined in include/xen/interface/xen.h
if __XEN__ is NOT defined:

include/xen/interface/xen.h:
  #ifndef __XEN__
  typedef struct shared_info shared_info_t;
  #endif
