+Subject: [PATCH] Added Apple NAT64 support when both ASIO_HAS_GETADDRINFO and
+ ASIO_APPLE_NAT64 ar defined
+
+* When calling getaddrinfo(), Apple recommends to set
+  AI_DEFAULT flags in hint.
+
+* iOS bug workaround: sometimes iOS getaddrinfo() returns a
+  non-zero scope ID for non-link-local addresses.
+  Workaround by forcing scope ID to 0 for non-link-local
+  addresses.
