It would be nice if all (or most) of these compatibility quirks could be
isolated to specific headers. The last time I proposed something in this
direction (see [1]) it quickly got shot down and didn't garner any
further reactions. There seems to be reluctancy to add further state to
the parser which directly goes against these suggestions.
