Yes, tell me about it... I don't think we can blame clang for those failures
anyway. Xen is relying on optimizations to do compile time validations, and
AFAIK this is a grey area. There's nothing in the C spec that guarantees you
that those calls will be removed.

Anyway, will send a new version shortly.

Roger.
