To support an approximation to C23's nullptr keyword I installed the
attached patch into Gnulib. To test it a bit I'm using the new c-nullptr
module in GNU diffutils, by preferring nullptr to NULL in the diffutils
source. See:
https://git.savannah.gnu.org/cgit/diffutils.git/commit/?id=09f8e2b0a92f3d25325f5b1df20384140261ee10
Assuming this works out, at some point I would like to change Gnulib
itself to prefer nullptr to NULL, due to nullptr's somewhat-better
properties. There's no rush of course.
With current c-nullptr Gnulib .h files would continue to use NULL rather
than nullptr, since we couldn't assume client code includes a <config.h>
that defines nullptr on pre-C23 platforms, so perhaps at some point that
could be improved as well.
