[Xcb] XCBSync build failur in x.org

[dave frost]

I have almost got X to build, but this i now my main problem.  Ive 
downloaded the source from the git repository so is all very recent.  
Also, Mesa 6.4.2 doesnt seem to have the arrayobj.c (or something) file, 
which version of Mesa works with X ?

Amy help sorting this out would be great.
