Additional info:

This works on Redhat 6.0, 7.0, fails on 7.1, 7.2 (and it looks like 7.3)  It
seems tar is now 'smarter" in old tar it printed diagnostic
tar: Added write and execute permission to directory b
now tar makes directory writable, writes files it needs to and 
then fixes permissions on directory as required -- only it seems to
not do this for a symbolic link.

Also, if directory only contains a single symbolic link it seems to 
work ok.
