I think most configure scripts on Windows were written using a text 
editor, i.e. by hand. Windows systems are pretty consistent, so the 
kinds of tests and searches that you need to do on *nix aren't needed. 
You can assume that the Rtools are installed, but don't rely on anything 
else. We're unlikely to drop tools from that collection, so this advice 
should last quite a while.
