Comment 13 for bug 693151

Also, I had issues while compiling the following:
    Display *xdisplay = XOpenDisplay(NULL);
    Window xrootwin = XRootWindow(xdisplay, 0);
    XSelectInput(xdisplay, xrootwin, KeyReleaseMask);
    XWarpPointer(xdisplay, None, xrootwin, 0, 0, 0, 0, (width / 2), (height / 2));
    XFlush(xdisplay);
    XCloseDisplay(xdisplay);

...maybe some missing header or linker parameter there?
