Hi Riccardo,

you must use sel_isEqual to compare selectors in portable code, i.e.,
  if (sel_isEqual(action, @selector(copy:)) || sel_isEqual(action, 
@selector(cut:)) || sel_isEqual(action, @selector(delete:))
While sel_isEqual is just an alias for == on Apple's runtime (and the GNUstep 
runtime, I assume), this need not be the case for other runtimes. In 
particular, for the old GNU runtime sel_isEqual is not equivalent to ==, as 
you've observed.
