The patch as you propose it is not enough, because you also need to
regenerate the configury stuff. Also, I think that anyone re-rerunning
the update-gnulib.sh script would end up overwriting your changes.

Rather than doing everything by hand and risk missing something,
I just propose we take advantage of our update-gnulib.sh script
instead. To do so, I've imported the commits from gnulib as patches,
and then updated the update-gnulib.sh script to include those two
import patches in the sequence. The patches had to be adjusted
a bit to the layout in the import as opposed to in the repository
of origin, but they are otherwise the same.

This is the first moment I've had to work on this, so the patch
hasn't been tested on our Windows machines yet. I expected to be
able to report on that mid-to-late next week. In the meantime,
if you could test this patch in your environment, this would help us
guarantee that things are good on your end too, now.
