Not officially. You should always use the latest XCode, no matter what, though.

Indeed, but we're changing policies. Users are expected to use the latest and 
greatest OS X and XCode, since they're now free for upgrading. I'm not sure 
whether this applies to 5.7 or not.

Still, note that this is not an error. It's a warning turned to error because 
of the -Werror, which means that you used -developer-build. In that case, 
please send a patch. :-)
