I've never seen this particular error in my cross-builds, and
I've been building all the changesets constantly since March.

Rather than try to debug this, how about getting a known-good
combination building?  I'm concerned that these errors are due to
a problem in your building process rather than issues that need
to be debugged in the tree.

I just successfully built this combination:

    xen-unstable.hg-17879
    linux-2.6.18-xen.hg-577

If this combination fails for you, could you provide the full log
of the build for perusal?

The full log of my build, including the commands used, is here:

    http://free.linux.hp.com/~agriffis/17879+577.log

In particular, the make command:

    make XEN_TARGET_ARCH=ia64 CROSS_COMPILE=ia64-linux-gnu-

This is running in a Fedora8 chroot with the cross-compiler and
sysroot installed as described on the wiki.

Thanks,
Aron
