When trying to compile any version of OpenLDAP from 2.0.1 to 2.0.4 I get a
following error:

os-ip.c: In function `ldap_connect_to_host':
os-ip.c:334: `INET_ADDRSTRLEN' undeclared (first use of this function)

I cannot find definition of this constant in the source files of OpenLDAP.
What's wrong?
Where is this constant declared?
