I forgot about builds on 32-bit architectures, which are filled with 
pointer aliasing warning spam reminding us how unsafe our code is. We 
don't have any EWS for those platforms, though, only regular bots 
(which, again, should definitely not use -Werror, because we don't want 
to lose a night of test results to a silly build warning).
