You can have Makefile in vignettes, and at the moment this even passes CRAN tests. You may also need to have a vignettes/.install_extras file to move the produced non-vignettes files to their final packaged location.

You still get warnings of unused, pointless and misleading files with R 2.15.3, because R 3.0.2 packaging process makes files that R 2.15.3 regards as pointless and misleading. The CRAN policy seems to be to ignore those warnings. R is not backward compatible with herself, and I don't see much that a package author could do to work around this (apart from forking the package).
