As the example you show in your patch demonstrates, there are even cases inside 
gcc that would be triggered by this patch. I believe it would therefore be useful. 
Also, jsm's response was not dismissive of the patch at all, though we would indeed 
have to have a Changelog entry as well as testcases.  
 
Joseph, would you mind commenting on the usefulness of an approach as mentioned 
in the patch linked from comment #1?
