You have probably got many reports of this bug, but I'll report it just
in case nobody else has. Gnutar 1.11.1 doesn't set the ownership correctly
for explicitly created directories when the user is root. The following
results are from a Sun SparcStation and an SGI Indigo.
Here is the contents of a test archive.
gnutar tvZf test.tar.Z
drwxr-xr-x 210/19 0 Nov 17 09:29 1992 test/
-rw-r--r-- 210/19 0 Nov 17 09:29 1992 test/f1
drwxr-xr-x 210/19 0 Nov 17 09:29 1992 test/d1/
drwxr-xr-x 210/19 0 Nov 17 09:29 1992 test/d1/d2/
-rw-r--r-- 210/19 0 Nov 17 09:29 1992 test/d1/d2/f5
-rw-r--r-- 210/19 0 Nov 17 09:29 1992 test/d1/d2/f6
-rw-r--r-- 210/19 0 Nov 17 09:29 1992 test/d1/f4
-rw-r--r-- 210/19 0 Nov 17 09:29 1992 test/d1/f3
-rw-r--r-- 210/19 0 Nov 17 09:29 1992 test/f2
user #210 = tam
group #19 = atmos
When extracting the archive as root, I get
gnutar xZf test.tar.Z
ls -lR test
total 1
drwxr-xr-x 3 root wheel 512 Nov 17 09:29 d1

As you can see, the directories have ownership root/wheel. However, if
you add the f_modified flag, you get the correct ownership at the cost
of changing the original modification time:
gnutar xmZf test.tar.Z
ls -lR test
