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.
