I don't know what's wrong with this except that I've noted cc1: warnings 
being treated as errors in your message and the xen build process is not 
warnings free yet.
What I propose is the following:
Beeing on debian the safest way is to install via debs, so I would 
recommend to search packages.debian.org for xen-hypervisor with 
distribution sid, download the source package, unpack it with 
dpkg-source -x .....dsc, then cd to the created directory and 
dpkg-buildpackage -rfakeroot.
This way I was able to compile xen on my etch box.

Good Luck!

Geza
