    Fix Leash build error with recent Visual Studio
    
    Visual Studio 2015 and later do not allow manipulation of the _flag
    field inside a file handle.  In Leash's out2con.cpp (used only for the
    debugging -console flag), do not try to mark the allocated file handle
    as free after copying it to *stdout; a one-time memory leak here is
    unimportant.
