undefined reference to `_ldap_int_resolv_mutex' compiling with Cygwin

["Matt Ross" <m.g.ross@herts.ac.uk>]

I have Cygwin 1.3.170-1 and GCC 3.2-3 and OpenSSL-devel 0.9.6h-1 that I
installed today. I am trying to compile the libraries and tools only of
OpenLDAP 2.1.9, as I am building a Windows GUI application to handle
adding and removing user accounts via LDAP. I have made sure GNURegex
4.4-2 is installed as per the FAQ and I was configuring like this:

CFLAGS="-fno-common" ./configure --with-tls --disable-ldbm
--disable-slapd --disable-slurpd

I used '-fno-common' as I have already read posts (mainly MacOS X
related) saying this fixed the problem I am having. For me it has made
no difference with or without this flag.

To make I do:

make depend; make

This eventually comes back with this error:

What else do I need to do to get this compiled?

Thanks,
