I think this is not ia64 specific, but generic issue.
It looks like msi-x related definitions are missing.
Greping under /usr/include tells me the followings.
The c/s 17605:4afc6023e8ec seems to assume that those definitions
are defined in user header files.
Probably updating those header files might fix your issue.
Or are you using non-Linux OS?
I suppose ioemu shouldn't depend on linux environment as some people
compiles on non-Linux environment.
thanks,
