+Subject: [PATCH] ping: Fix AI_CANONIDN usage on some systems
+
+Commit 99f67db used AI_CANONIDN in a way, which broke compilation on
+systems where AI_CANONIDN is not defined in netdb.h (e.g. glibc < 2.3.4,
+alternative libcs that don't support IDN: e.g. current musl 1.1.19 and
+uClibc-ng 1.0.30) when not using the system libidn2.
+
+Fixes: 99f67db ping: Fix ping name encoded using ACE on C locale
