Comment (by cooljeanius):

 Replying to [comment:2 ryandesign]:
 > The flags being used—`-std=gnu++11 -std=c++17 -std=gnu++11`—mean that
 C++11 mode (with GNU extensions) is being used whereas `make_unique` is a
 C++14 feature.

 Hm, the port already sets:
 {{{
 compiler.cxx_standard 2017
 }}}
 ...so I wonder why the build system doesn't respect that?
