Help me decipher these "WARNINGS" when repairing permissions....

[Jerry®]

I get this when I repair my permissions - anyone know what the ERRORS mean?

Permissions differ on "sbin/restore", should be -r-xr-xr-x , they are -r-sr-sr-x .
Warning: SUID file "sbin/restore" has been modified and will not be repaired.

Apple says, about these type of messages,
"you can safely ignore these messages. They are accurate but not a cause for concern."
