php ldap wit exop patch and missing ZSTR

Dear all, I'm trying to apply the php ldap EXOP patch from : <http://www.sys-net.it/~ando/Download/#PHP> The patch defines a zstr in ldap.c at line 1731 as obvious below. ZSTR no longer appears to be defined anywhere in php or zend.h - can somebody help me with this? Should i just define it manually?
