R devel - Nov 2010 - CRAN package archives (tar.gz) now require --no-same-owner under Windows?

Hello,

I have observed with the latest version of Rtools and R 2.12.0 under
Windows Vista or Windows 7 (64bit) that tar issues
errors of the form
"cannot change ownership to uid 1001, gid 100: invalid argument"
when one uses:

tar -xvzf pkg_version.tar.gz

There is an easy work-around:

tar --no-same-owner -xvzf pkg_version.tar.gz

Another possibility is to use an environment variable:

set TAR_OPTIONS=--no-same-owner

Curiously, this error message does not appear when I
extract package archives that I have created myself, so it
appears to be related to the particular environment and
tools used at CRAN to create package archives.

Any tips or ideas?

Thanks,
Dominick
