-Subject: [PATCH] Fix build failures for MariaDB 10.2
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-<mariadb_version.h> does not exist in mariadb-5.5.26. Do not include
-it explicitly. Instead rely on including <mysql.h> that transitively
-includes <mariadb_version.h> or <mysql_version.h>. This makes this
-patch more portable.
