It's a long time since I've used the IL backend, I'm glad to hear it
still works, but yes I think we do output both of those wrappers if the
file contains any pragma foreign_* stuff.

If you don't  mind me asking, what are you planning to do with Mercury?
And why you need the IL backend?

It is still a goal of mine to improve the support of both the IL and
java backends, but unfortunately our current projects at work don't
require them.
