Another solution is to have the first entry be the special case, instead of the last entry:

std::string Compose(DataItemList& dilList)
{
    std::stringstream ssDataSegment;
    for(iterItems = dilList.begin();
        iterItems != dilList.end(); 
        ++iterItems)
    {
        // See if current element is the first
        if(iterItems == dilList.begin())  
        {
            ssDataSegment << (*iterItems)->ToString();
        }
        else
        {
            ssDataSegment << "," << (*iterItems)->ToString();
        }
    }
    return ssDataSegment.str();
}
