It turned out on enquiry that Tomas Kalibera of R-core already had 
prepared an updated Windows RTools bundle for SVN commits 6335-6327 that 
is queued for assessment for the main R Windows package static build 
train, and for signing before release. It includes GDAL 3.9.3. Using that 
draft toolset, I built locally an sf binary for Windows and have passed it 
to Abel offlist for testing and preliminary deployment.

Tomas also pointed to hot-fixes needed with 3.9.3 in pkg-config in that 
setting to remove ".lib" from "-lshell32.lib" and "-lole32.lib" - towards 
end of:

If these file extensions as such are not needed in other settings, maybe 
they could be suppressed in the next RC?

There are other patches too, most masking "int main(...)" in apps, and 
fine-tuning Cmake behaviour, and listed in 
https://svn.r-project.org/R-dev-web/trunk/WindowsBuilds/winutf8/ucrt3/toolchain_libs/mxe/src/gdal-1-fixes.patch 
and needing intervention at each upgrade.
