I agree that an upstream report would be nice, but it has been a 
long-standing policy of not changing 3rd party code to fix warnings, but 
instead suppress them. (Most of the time we compile with a much larger 
set of warnings enabled than the upstream's own build does, so we 
trigger warnings they never even see.)
