You have to tell the compiler explicitly that
the Version() method does not alter the FOO
object since the PrintVer function gets a
const pointer.

Methods which really do notalter the internal
state of an object should always be declared
const like:

<snip>
int Version() const {
  ....
}

</snip>

Hope that helps
