I think newer libarchive-based bsdtar should be fine. Ubuntu 9.04 has:
$ bsdtar --version
bsdtar 2.4.17 - libarchive 2.4.17
Set down the requirements and build a list of the tar programs that have been
found to work on various platforms (and explain how to tell tlmgr which
one you want it to use).

GnuWin32 has a libarchive bsdtar with installer:
bsdtar 2.4.12 - libarchive 2.4.12
works for me extracting a tar file with long names that fails
using the tar.exe from TL2009, but bsdtar fails when I try to
create a .tar archive from the same tree on Win32. The
current stable version is 2.7.1.is at:

<http://drupal.org/node/483110> recommends the tar.exe from mingw:
<http://sourceforge.net/projects/mingw/files/> has a tar-1.22, presumably
based on GNU tar.
