Utility:	gnu tar 1.11.1
System:		Sequent Symmetry S27
OS: 		dynix 3.0.17.9
Source:		ftp.uu.net:packages/gnu/tar-1.11.1.tar.Z

When extracting files from an archive as root (tar xvpf), the owner
and group are not preserved on directories.  This makes it impossible
to use gnu tar to copy a directory subtree to another location:

	cd /foo ; tar cvf - . | (cd /bar; tar xvpf -)

NOTE:  If the -m flag is included to the tar extract command (tar
xvpmf), owner & group are preserved, but modification times aren't.

Included below is a patch which I think will fix the problem.
