Well the patch seems to work -- no error messages.  Don't know about
any other details than that.  The file perms are a combination of
rwx for user and group and nothing for 'other', despite there being
no 'default' acl. 

Also, I was able to take a tar from cygwin with acls+xattrs, and
extract it on my samba server and have the permissions recreated
on linux as they were on windows!

That was a first.  Not all of the utils work so well, but tar
restored my win-perms on linux.  Rather neat.
