tar --remove-files chokes on symlinks

[lrhorer <lrhorer@satx.rr.com>]

I have a cron script that runs tar on a directory in order to clean it 
up and minimize its size.  I run the command:

tar cf Backup_Server.tar.gz --remove-files *

but during the tar process I get the errors:

tar: /RAID/System/Backup/bin: Cannot rmdir: Directory not empty
tar: Exiting with failure status due to previous errors

When I look in /RAID/System/Backup/bin, all that is left are a number of 
symlinks.  Evidently, tar is unable to delete the symlinks prior to 
attempting the directory delete.  If it makes a difference, these 
symlinks actually point to nothing.  In any case, how can I get tar to 
delete the links and complete the job?
