In addition to these steps, we should run through the list of containers here: https://r-hub.github.io/containers/

...since the main issue in this release will be build failures related to (1) lack of cmake or (2) lack of (a sufficient version of system) Abseil or (3) patches required to vendored Abseil to avoid check failures with compilers we haven't thought of yet.

atlas (Fedora 38) gives:

# docker run --rm -it -v `pwd`/check:/check ghcr.io/r-hub/containers/atlas:latest bash
# # dnf install cmake
# # r-check
Found the following significant warnings:

See ‘/check/s2.Rcheck/00install.out’ for details.

I'm fairly sure we fixed the zero-size array thing in the previous version and can patch the raw_hash_set in the vendored Abseil.
