Comment:

 There are now two proposals.
 1. `-stdlib=libstdc++` refers to MacPorts libstdc++ if variant if selected
 1. `-stdlib=macports-libstdc++` refers to MacPorts libstdc++ if variant is
 selected
 For my needs, it makes no difference.[[BR]]
 I am new to clang/llvm code, so any feedback would be appreciated.
