     * The class is not actually defined in the
     * \link ::platformstl platformstl\endlink namespace. Rather, it
     * resolves to the appropriate type for the given platform, relying on
     * \ref section__principle__conformance__intersecting_conformance "Intersecting Conformance"
     * of the resolved platform-specific types.
     *
     * When compiling on UNIX platforms, the platformstl::system_traits
     * type resolves to the unixstl::system_traits class. On Windows
     * platforms it resolves to the winstl::system_traits class. It
     * is not defined for other platforms.
