I am trying to compile the rsync tree using SuSE linux 7.3 which is getting
a little long in the tooth, and has a 'xf86dga.h' file that starts like this:

/* $XFree86: xc/include/extensions/xf86dga.h,v 3.20 1999/10/13 04:20:48 dawes Exp $ */

#ifndef _XF86DGA_H_
#define _XF86DGA_H_

#include <X11/Xfuncproto.h>
#include "xf86dga1.h"

The problem is is the last line shown which in later versions of this file is:

#include <X11/extensions/xf86dga1.h>

Now I appreciate that it might make sense to upgrade to the required version, but there
is a case for OS projects to be as developer friendly as possible, would be desirable to
(at least in some cases have the include directories set by configure to have
'-I/usr/X11R6/include/X11/extensions/' as well as '-I/usr/X11R6/include'.
