Well, maybe they should, but right now they don't, and neither does
your patch add any such correction.  The point I was trying to make
is that therefore, your patch as it is, while fixing one class of
bugs on some targets, may simultaneously introduce a different class
of bugs on other targets.  I'm not sure this is a good idea ...
