Searching for "64 bit" in the Writing R Extensions manual finds a lot of 
advice, especially in the "Writing Portable Packages" section.  I'd 
start there.  There's also some advice in the Windows FAQ and a 
description of (and links to) the necessary tools on my 
www.murdoch-sutherland.com/Rtools page, and in the "Building R for 64 
bit Windows" section of the admin manual.
