Why are you so selectively quoting the standard so as to miss out the 
immediately preceding text "such that if one member of a corresponding 
pair is declared with a name, the other member is declared with the same 
name."?

We know there are problems with the type compatibility rules for 
structures across translation units

isn't such a problem.
