I'm not getting this warning neither on x86_64-linux nor on i686-linux, otherwise I would not have committed the patch. Any information about the platform you are getting the warning on would be appreciated. If you can reproduce it, can you check whether providing option -stdÉ0 or something like it would suppress it?
