	I thought you spent some time doing work to make this unnecessary and
AFAIR at the time I pointed out that you wouldn't be able to add
instance data, anyway.

	Sigh; what headers does gail install currently ? seemingly none - that
seems good, but ...

	I suppose the release team need consulting - there are rumblings going
on over there; either way I have no particular conceptual problems with
gtkhtml2 depending on gail, or gail exporting some minimal API to help
code re-use.
