[Rd] configure.ac

[peter dalgaard]

If you check developer.r-project.org, you'll find links to the scripts that we use for building releases and pre-releases of R. These are usually run on a Mac, but shouldn't require much change for Linux. In particular, notice this lead-in in the prerelease script:

rm -rf BUILD-dist
mkdir BUILD-dist
cd R
aclocal -I m4
autoconf
cd ../BUILD-dist
....etc....
