[R] trouble with installing R-2.12.0 from source on Windows

[Prof Brian Ripley]

Having managed to reproduce this with the current Rtools212, I needed

tar -zxvf --no-same-owner  R-2.12.0.tar.gz

(or -xf: the 'z' is optional, and --no-same-permissions would also be 
a useful sanity check).

Although the messages are unclear, they do seem merely to be notices 
not errors.
