If look closely enough at _Writing R Extensions_ you notice that it mentions 'configure.win' over half a dozen times. A powerful trick is to then use the fact that there are other packages on CRAN, in fact almost 18k of them.
And e.g. this search https://github.com/search?q=org%3Acran+configure.win&type=code find 261 hits within the 'cran' mirror at GitHub for the term 'configure.win'. Some of those are likely of use to you.
