It's certainly not our intent to include such changes for their own 
sake.  However, such changes to occur, usually in the course of fixing a 
regression of some kind.  If the code in question is actually invald, as 
in your examples, then, no we do not worry about that.  Trying to fix 
regressions while simultaneously preserving buggy, undocumented behavior 
is simply too hard.  If you require the full behavior of a particular 
GCC release (including both its strengths and its weaknesses), then the 
only practical choice is to carry around that your release yourself.
