Many thanks. I've not tried this patch yet, but it looks like it's not
made the development version of RGtk2, which is what I had been working
with. I will try out the archived RGtk2_2.20.36.3.tar.gz

This is helpful to know, as it suggests that if RGtk2 could be updated
to work with Gtk4, installed into MXE, and if the Mac recipies could be
updated, the changes RTools might be accepted, and then RGtk2 (perhaps
renamed RGtk4) might be uploadable to CRAN.
