OK. After all, ref-filter.c has too many existing global variables (starting from the used_atom[] array) that makes it impossible to be a proper API that can be used to handle more than one invocations at once, so two more globals aren't making it any more hopeless than it currently is. If we wanted to make the API reentrant, we'd need a bigger change anyway. > Or just use "static" prefix? Yes, that is needed regardless to pass "make sparse". TShanks.
