It will present a problem to the xsplice-tools.git which are outside
the tree. Right now they have their own header file (which mirrors this
one). But if we make it unstable and start mucking around then folks
using the tool would need to pass parameters for 'what version' is

I would rather not have this happen - and now that we do not need
the #ifdef BITS_PER_LONG we can also remove the __XEN__ conditional.

Either way, this is something that can be done later.
