Peter Hutterer 3aca819940 dmx: force -fno-strict-aliasing for xinput example 
Compiler warning:
xinput.c:272: warning: dereferencing pointer 'e' does break strict-aliasing
rules

The code itself is the usual XInput client-side code:
        XEvent event;
        XDeviceMotionEvent *e = (XDeviceMotionEvent *)&event;
        XNextEvent(display, &event);
        printf("%d\n", e->type);

Since XDeviceMotionEvent is not guaranteed the same size as XEvent, clients
must use pointer aliasing as above when using the XNextEvent API. Disable
strict aliasing for this example.
