[archive] Fix unused parameter warning

[schlotter]

Hi!

The function parameter to `bool tracking(const unsigned
int flags) const' in `archive/detail/oserializer.hpp'
is currently unused.  The attached trivial patch
against HEAD[1] fixes this.

Regards
Christian

Robert, coincidental I saw your reply on the mailing list
archives.

For convenience, the function definition we're talking about:
    virtual bool tracking(const unsigned int flags) const {
//        if(0 != (flags &  no_tracking))
//            return false;
        return
boost::serialization::tracking_level<T>::value ==
boost::serialization::track_always
            ||
boost::serialization::tracking_level<T>::value ==
boost::serialization::track_selectivly
            && serialized_as_pointer();
    }

As you can see, the part which uses the parameter is
commented out.  So, the parameter may be used, but it is
ignored in the function body.

Regards
Christian

I just noticed that I missed a similar warning.  The second
attached patch fixes this too.

OK - I've applied the patches to my local copy which will be
uploaded to
CVS/Head.  Sorry this won't show up in boost until version
1.35.  So if this
is important to you, you should patch your own copy.
