Thread-topic: Is unmodified_drivers broken? 
All,
I tried to compile unmodified drivers on the latest changeset (14631).
The compile breaks.
This is what I did.
I booted up a x86_64 hvm domain that was running sles 10, I copied the
entire xen-unstable tree into the domain.
Then, I went into the unmodified_drivers directory and ran mkbuildtree
and make -C /usr/src/linux M=$PWD V=1 modules .
I have posted the results. 

- Have others seen this issue?
- Is this because of some kind of mess up where the
/usr/src/linux/include/xen directory is clashing with the local
include/xen directory? 
Looking at the overrides.mk file, it does seem like the local directory
is getting included first.

Thanks
Raj

Defaulting to this machine's architecture, x86_64, for linking.
This may be overridden on the command line (i386,x86_64,ia64).
