Yep, this was a bug in the 3.0.2 xen tree. There's three ways you can deal
with it. 1. Edit the source code to add in the extra 'case PTRACE_SETOPIONS:'
statements in the switch statement. 2. Edit the makefile to remove -Werror and
just ignore the warning, hoping nothing bad will happen. 3. Upgrade to the
newer 3.0.3 / 3.0.4 releases. Personally I'd recommend the latter since there
has been soo much important development work in scalability, performance, not
to mention countless security fixes in the newer releases. And that's ignoring
the huge advances in the quality of HVM support & userspace tools.
