Version:6.1.6 OS:Any
Assigned to: CPU Architecture:Any

Description:
The Connector/C-6.1.6 release changed mysql_com.h from
#define CLIENT_SECURE_CONNECTION 32768
(like in MySQL 5.6) to
#define CLIENT_RESERVED2 32768
like in MySQL 5.7

This should not be done with an API/ABI targeting 5.6

How to repeat:
Include mysql_com.h
