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
