true for windows c compilers, independent of the ddk.

well, gcc built the xen binary under this assumption, right?

indeed. it's still about the add_to_physmap issue you described? 
will need a fix then to adjust the xen_ulong_t typedef accordingly on

correlated question from my side: what is xen_ulong_t good for?
shouldn't the public headers use either stdint or a more descriptive
typedef? ulong_t sounds pretty redundant to me, especially when
typedef'd to an 'unsigned long'.
