      Description

      MariaDB will try to parse and execute SQL inside, for example,

      /*!50701 ... */

      comments. Because, when compared as versions, 5.7.1 is less than 10.0.4. But in fact, MySQL-5.7 has new features and might have new SQL syntax that MariaDB-10.0 does not understand.

      To fix this MariaDB-10.0 will ignore all versioned comments with MySQL version in the range 50700–509999.

      If a user wants to use a feature that is in MySQL 5.7 and MariaDB 10.0, he can use
      repeating things for both releases:

      SELECT /*!50701 aaa */ /*!100101 aaa */

      or use the MariaDB syntax (if he is only using MariaDB):

      SELECT /*!M50701 aaa */
