Thanks for that pointer.  Could you consider "just" using Linux for now?

Doing Windows is entirely doable, but more involved.  As I recall, you need
tricks such as not using a configure.win in order to build with both default
arches on Windows.

There are packages that do this, and you can "borrow" solutions from them.
But none springs to my mind rightaway as I tend to deploy on Linux first, or else
work with the very kind CRAN folks and have them provide 32 and 64 bit
libraries on the builders themselves (as eg recently with hiredis) :)
Medium-term you could do this too as libS3 is open source.

Until then you can of course emulate that scheme perfectly well by building
the 32 and 64 bit DLLs, store them in your repo and have Makevars.win point
to them via the same env var trick used at CRAN.
