CRAN package slider

[Kurt Hornik <Kurt.Hornik@wu.ac.at>]

Davis,

Please see

  <https://cran.r-project.org/web/checks/check_results_slider.html>

Unfortunately, in addition to the new strict-prototypes compilation
warnings in r-devel we also have test ERRORs for the Debian r-patched
and r-release checks, which also materialize in the autopkgtest checks
for the r-cran-slider package and thus currently prevent the migration
of the new R 4.2.2 Debian packages from unstable to testing, see

  <https://tracker.debian.org/pkg/r-base>

My hope is that this can be overridden quickly to get the Debian
packages migrated to testing, but in any case, can you please fix the
ERRORs (and ideally also the compilation warnings) as quickly as
possible?

Best
