Aren't you two in violent agreement?  I think Bruce now understands
why changequote doesn't work, and he is thinking of a new GNU M4
feature that should do what he wants.  This feature cannot be
implemented in terms of changequote; it has to be a primitive.

Obviously users can't employ the proposed GNU M4 primitive in Autoconf
now, since it doesn't exist yet, but I don't see why it would have to
be avoided if it did its job well.
