I think we should take different approaches for master and branch.

  - On master, we should attempt a gnulib update, so as to keep
    out list of patches down to the absolute bare minimum.

    Alternatively, if there is an unforseen complication with doing
    that, we could include those two changes as local patches
    specifically, but this would only create more work for the next
    person who wants to do an update. That's why I think we should
    first try the regular update.

  - On the branch, I think we should go with Bruno's patches,
    after review and testing. gnulib updates are always tricky,
    so outside of some particular circumstances, I think they are
    in general too risky to do on a release branch.
