tar attempts to change ownership to invalid uid.

[akf@…]

When running as root, untaring the boost package using gentoo prefix on Interix v3.5 for Windows XP fails with:

Cannot change ownership to uid 501, gid 0: Invalid argument

This is solved by running tar with flags:

"--user root --no-same-owner"

This issue is unique to boost .tar.gz files and blocks any installation by gentoo emerge.

The work around only needs --no-same-owner
