I would appear that I had forgotten that I had half-fixed that. My
~/.R/check.Renviron contains this at the end

[... stuff omitted ...]
#
# edd Apr 2019
_R_CHECK_COMPILATION_FLAGS_=TRUE
_R_CHECK_COMPILATION_FLAGS_KNOWN_="-Wno-class-memaccess -Wno-ignored-attributes -Wno-misleading-indentation -Wno-unused"

so presumably carrying that line over would help. Sebastian Meyer also kind
sent me pretty mich the same line off-list which he had added to his ~/.Renviron.
