I'm going to try and reporduce the r200 display list problem after the
various build problems are fixed.

It builds fine on my main machine. I tried a build on a fresh system
install (with X.org CVS installed) and hit the same problem. I
committed a fix for it just a few minutes ago. I think the problem here
is related to the next problem...

The only way this could happen is if *both* PTHREADS and XTHREADS are
defined. I suspect the Xthreads.h problem was always there, but it was
never hit because XTHREADS was never defined. Some how, somewhere,
XTHREADS is getting set. I'll have to look into it, but I think this is
a bug in whatever X.org header is defining XTHREADS for us. :(
