 Description   

The LGPL client lists "my_bool unused_1" where, in previous versions of MariaDB 10.1 and MySQL libmysqlclient, this was "my_bool reconnect"

Here is a PR for perl-DBD-MySQL, that contains more than changes for this regression.

+/* MariaDB Connector/C has MARIADB_VERSION_ID instead of MYSQL_VERSION_ID */
 
+#if !defined(MYSQL_VERSION_ID) && defined(MARIADB_VERSION_ID)
 
+#define MYSQL_VERSION_ID MARIADB_VERSION_ID
 
+#endif

I am not sure if 'myssing MYSQL_VERSION_ID' is also a 'regression' or not.

MYSQL_VERSION_ID was added already: https://github.com/MariaDB/mariadb-connector-c/commit/422d0f786e5e6eb103000a75738322c8baa9aa12

This is intentional, direct access to MYSQL members is being removed, one should use accessors instead.
