That's odd. I just pulled a fresh copy of xen-unstable and built xen and the tools. Both compiled with no errors or problems. Maybe this is some sort of distro-dependent problem?

The series of 46 patches attached to this email contain the initial
implementation of memory paging and sharing for Xen. Patrick Colp
leads the work on the pager, and I am mostly responsible for memory
sharing. We would be grateful for any comments/suggestions you might
have. Individual patches are labeled with comments describing their
purpose and a sign-off footnote. Of course we are happy to discuss
them in more detail, as required. Assuming that there are no major
objections against including them in the mainstream xen-unstable tree,
we would like to move future development to that tree.

I'm getting compile errors:

The first is easily fixed by adding #include <unistd.h>, but I haven't looked into the second yet.

Thanks,
