+Subject: [PATCH] Include <array.h> for std::array
+
+When compiling using clang/libc++ it fails to build because this header
+is not included, with libstdc++ this seems to be pulled in
+automatically.
+
+Fixes below error
+
+apt-pkg/contrib/strutl.cc:949:38: error: implicit instantiation of undefined template 'std::__1::array<const char *const, 7>'
+   std::array<char const * const, 7> c_weekdays = {{ "sun", "mon", "tue", "wed", "thu", "fri", "sat" }};
