Sorry - I experienced the error on a production box running Debian 
packages, and re-built from source on my local machine just to confirm 
the bug still exists. However, my local machine already has other LDAP 
libraries installed which seems to have resulted in some of the wrong 
libraries being picked up at compile time.

I've now removed all pre-built openldap packages, re-built again from 
source and can confirm that the bug still stands since the 
"ldap_int_global_options" warning has now disappeared:
