Adding "-std=gnu11 -std=gnu++14” to CXXFLAGS is sufficient for me.

Ben,

Does clang really need -std=gnu++14?  The documentation at http://en.cppreference.com/w/cpp/memory says that unique_ptr is a part of the 2011 standard.  Now it may be that clang does not implement the full 2011 standard--that seems to be the case since the autoconf macros did not detect that you had a 2011-compliant compiler.  The piece of code getting used, std::autoptr, is valid until 2017 so it may be that sometime in the next year clang will be updated to be 2011 compliant.

Yes. Without -std=gnu++14 I got an error. I can try again and provide specifics if you like.
