This dependency is actually a bug that was introduced in the Xen tree 
(it isn't present in qemu CVS).
The VNC spec makes it pretty clear that you cannot rely on the symbolic 
names of X keycodes to develop a portable VNC client.  Apparently they 
change slightly across different X implementations.
When I wrote the original VNC code for QEMU, I was careful not to rely 
on include files because of this.  We should really remove this 
dependency and hard code the keycodes ourself.
