It would not be feasible to ifdef all the calling c code.
In this case the change in behaviour won't be very large, so one could
update the LGPL version so that they're interchangeable again. But the
question was really about, what if I import a function different enough
that I don't volunteer to do that update?

the general case, filter_mb()
