If we implement that, and sqldb is installed

Laz --> mysql40conn (tmysql40conn) --> mysql40 (pmysql, mysql_init())
        mysql41conn (tmysql41conn) --> mysql41 (pmysql, mysql_init())
        mysql50conn (tmysql50conn) --> mysql50 (pmysql, mysql_init())

Lazarus uses the mysql40conn,mysql41conn and mysql50conn units, they all
use a different mysql-unit, but all those units implement functions and
procedures with the same name, but with other arguments. 

I'm not sure it the compiler will allow that?
