 * File:        winstl/filesystem/findvolume_sequence.hpp
 *
 * Purpose:     Contains the basic_findvolume_sequence template class, and ANSI
 *              and Unicode specialisations thereof.
 *
 * Notes:       The original implementation of the class had the const_iterator
 *              and value_type as nested classes. Unfortunately, Visual C++ 5 &
 *              6 both had either compilation or linking problems so these are
 *              regretably now implemented as independent classes.
 *
 * Created:     15th January 2002
 * Updated:     21st June 2010
