Right. 

Indeed I did not realize that each and every portfile would be examined for cxx_stdlib overrides for each different system configuration, and that would be integrated into the check mechanism for the build.

So if he had wanted to (and assuming the linkages worked out), Zero could have also just as correctly put 

configure.cxx_stdlib libstdc++

into his unar portfile, and left things alone.
