I've bumped that to size_t here, as well. I agree that bumping it to `size_t` would be sensible, but it doesn't look like you actually followed through with that change, as... > diff --git a/prio-queue.h b/prio-queue.h > index 4f9a37e6be..36f370625f 100644 > --- a/prio-queue.h > +++ b/prio-queue.h > @@ -30,7 +30,7 @@ struct prio_queue { > prio_queue_compare_fn compare; > unsigned insertion_ctr; ... it still says `unsigned` here. I was surprised by how few callers there are required any changes due to `.nr` changing. I scanned through the code and found one more instance where we have to adapt code, in commit-reach.c:queue_has_nonstale(). The compiler does not generate warnings for this case because the file isn't -Wsign-compare clean yet. Anyway, I see that the patch has landed in "master" already. Let me send a follow-up patch series to fix both issues. Patrick
