Just an FYI. Without the XXXXat() system calls Samba
will never be safe against symlink attacks on this
platform (neither will any other user-space code,
so I don't feel particulary picked on here :-).

Please explain this to any users of your port,
so they only expose files over SMB2+ (which renders
them safe vs. SMB symlink attacks, but not local
ones).
