I've committed changes to the OpenLDAP repository such that OpenLDAP libraries and client tools now build successful (and appear to run okay) on Cygwin B20.1 w/ EGCS 1.2.1 running under Windows NT4 (sp5). I consider this port highly experimental... For details on how to build the system, see: http://www.openldap.org/faq/index.cgi?file=145 Kurt
