Sure, but now with Gnulib, ignore_value (E) is the new idiom for (void) 
(E). A careless developer blindly applying ignore_value now is like a 
careless developer blindly applying a void cast in the good old 
days.Nothing has changed, really.

If GCC changes again in this area, I hope Gnulib's ignore_value 
continues to work. It would be a pain to have yet another musical-chairs 
period during which there is needless confusion.
