MySQL 5.6 Release Notes
This program is obsolete. It is deprecated as of MySQL 5.6.19 and is removed in MySQL 5.7.
The normal way to report bugs is to visit http://bugs.mysql.com/, which is the address for our bugs database. This database is public and can be browsed and searched by anyone. If you log in to the system, you can enter new reports.
In the header of that script is the actual "configure" statement that has been used to produce your version of that server with all options. If you want to verify what has been compiled in or which pathnames have been set to what defaults, this is a good place to look.
