Error Compiling kvm-userspace

[Mohammed Gamal]

Hi,
I was trying to compile the code from kvm-userspace.git against the
kernel from kvm.git tree. I ran configure --with-patched-kernel and I
got this error:

Last commit broke libkvm.  I pushed out a fix.

Any sufficiently difficult bug is indistinguishable from a feature.
