Using a simple (type *) cast on g_list_next results in a warning with modern compilers "old-style cast" Adding a warning for g_list_next and data access to avoid the warning A good overview why reinterpret_cast has been used can be found here: https://stackoverflow.com/questions/332030/when-should-static-cast-dynamic-cast-const-cast-and-reinterpret-cast-be-used It is a 1:1 replacement in this case, but does not use any of the new cast styles and therefore should be used with caution.
