mysql_init() was introduced in MySQL 3.22.

Fix:

Remove all calls from mysql_init() in your program!

Note that as you don't get any warnings that 'mysql_init' is
undefined, there is a change that you are linking your programs with
include files from MySQL 3.22 !
Please verify that mysql.h doesn't have any references to 'mysql_init' !
