So we got link error:apr_dbd_mysql.obj :

symbol _my_init referenced in function

fatal error LNK1120: 1 unresolved externalsAs
in dbd_mysql_open, we call mysql_init, 

which call mysql_server_init, then
mysql_server_init call my_init,so 
we need not to direct call my_init.This issues
exists in 1.3.x, 1.4.x, 1.5.x and trunk.Index:

i have tested this patch, it does compile, but 
then apache crashes when calling dbd_mysql_init

i found the solution to call mysql_init() and 
then destroy the created object with mysql_close()
 i left it like this, and now it works apparently 
with no problems.

MYSQL * temp_ptr = NULL;
temp_ptr = mysql_init(temp_ptr);
