+** The preprocessor flag LDAP_API_FEATURE_X_OPENLDAP_REENTRANT can
+** be used to determine if -lldap is LDAP_API_FEATURE_THREAD_SAFE at

+**             LDAP_API_FEATURE_OPERATION_THREAD_SAFE
+**
+** The preprocessor flag LDAP_API_FEATURE_X_OPENLDAP_THREAD_SAFE
+** can be used to determine if -lldap_r is available at compile
+** time.  You must define LDAP_THREAD_SAFE if and only if you
+** link with -lldap_r.
+**
+** If you fail to define LDAP_THREAD_SAFE when linking with
+** -lldap_r or define LDAP_THREAD_SAFE when linking with -lldap,
+** provided header definations and declarations may be incorrect.
