Patch for ldap.c under Windows. It works with wldap32.dll as supplied with
Win-98/ME/2000/XP, so no extra .dlls are required.  I've mostly tested it
against Verisign's ldap server. Added code in the case there are to many
responses (rc = LDAP_SIZELIMIT_EXCEEDED) and print only those we got. E.g.

curl
ldap://directory.verisign.net/?cn,display-name,mail,info?subtree?(cn=*Nelson*)

will print the first 10 results.

My only problem with it is that ldap_search_s() fails with "filter error" when
CURLDEBUG is defined ?! Maybe someone can spot the error.
