> The conversion at the other end, TAG_PTR, suffers from the same potential problem but in reverse, which is perhaps less obvious to the casual C programmer but nevertheless a danger of the same kind, so we'd better do something about it as well. I'll be back with a proposed patch.

Here it is. Very straightforward: just flip a cast and remove unused definitions.
