I've spent a few days revamping the Makefiles for the Windows installer. It looks to me as though it works, but I've probably made some errors or omissions. Anyone interested in testing it is invited to download it from my web page, <http://www.stats.uwo.ca/faculty/murdoch/software/r-devel> As the readme file on that web page says, "I'm not doing clean builds each time, so it's possible the distribution will include some files that don't belong there; if so, please let me know. (Also let me know if files are missing!) There are likely to be numerous bugs in the snapshot. Don't trust it for important work." Duncan Murdoch
