Re: diffs to port code to gcc 6

Mike,

One question about this diff:

diff --git a/src/ov-class.cc b/src/ov-class.cc

+++ b/src/ov-class.cc

+        return !!os;
 
       i++;
     }

In all other cases throughout the diff file, "return os;" has been
translated to "return ! os.fail ();".  Is there a reason this single
instance is "return !!os;"?
