2.1.8 doesn't work on windows 2000

[Ugen <ugen@xonix.com>]

I have compiled 2.1.8 on windows 2000 , but when
attempting to run it, i get the following:
------------------------------------

starting slapd...
OpenLDAP 2.X Standalone LDAP Server (slapd)daemon_init: <null>
daemon_init: listen on ldap:///
daemon_init: 1 listeners to open...
ldap_url_parse_ext(ldap:///)
daemon: initialized ldap:///
daemon_init: 1 listeners opened
slapd init: initiated server.
bdb_open: initialize BDB backend

=> ldap_dn2bv(272)
<= ldap_dn2bv(cn=subschema,272)=0
<<< dnNormalize: <cn=subschema>
error loading ucdata (error -127)
slapd shutdown: freeing system resources.
slapd stopped.
connections_destroy: nothing to destroy.

---------------------------

I have 2.0.27 running successfully in similar 
configuraton (actually - no configuration at all,
just an empty database and test root dn).

Before i start debugging this thing - ideas?
