Yes that is right.  It was intentional but would change in the future.
XFree86 depends too much on an OS kernel features and low level
hardware.  This was the reason, most of the developers had thought
that XFree86 cannot work on Windows because it would violate Win32
hardware ownerships.  I did make some functions pass bogus stuff, but
it will change in future as we make more progress.  One of the feature
was OpenGL GLX.  I was under the impression OpenGL GLX with DirectX
would not work on Windows, therefore I was using stubs for OpenGL GLX.
Now it is fixed and works.  I will take fix other functions passing bogus
stuff
one by one.

chown() and chroot() are needed for Xfree.  Chroot() for now in our
X-servers is a stub.  On startup X complains that /tmp/.X11-0 should be
owned
by root, but still works, on UNIX if /tmp/.X11-0 is not owned by root, it
quits.
