Comment (by kencu):

 this was fixed years ago, and it is not broken now.

 {{{
 #include <atomic>
 }}}

 requires a c++11 capable compiler that is put into c++11 mode and building
 against a c++11-capable standard library.

 For most of macports that is {{{clang++ -std=c++11 -stdlib=libc++}}}.

 For gcc7, you should not have to do anything much as it defaults to c++11
 and also a c++11-capable stdlib. You would only have to make sure you
 don't screw up the defaults somehow by being too clever about things.
