Oh, I just thought because of your

I wasn't quite sure about integer(?) constants, but the compiler makes a
difference then between

  gui(GUI_SET_STATE, (void *)(filename ? GUI_PLAY : GUI_STOP));

and

  gui(GUI_SET_STATE, (void *)GUI_PLAY);

Weird. In both cases, only / the same constants are involved.

No. The X11/GTK GUI code compiles (even with a few more than the usual
compiler warning options) free of any warnings here. If not, I would have
fixed already.
