Hello Daniel,

Ahhh, the penny drops.

I have changed the code to the following and post it here for those who
may follow:

    bfs::path p( "." );
    bfs::directory_iterator dir_iter( p ), dir_end;
    for_each( dir_iter, dir_end, boost::bind( &purgeOlder, _1 )  );

@Ovanes: I saw your post and appreciate the effort, thanks :-)
