  range increasing the number with 10 for every step. Requested by Jose:

since IPv6 support is required.

Added -D'efines'.

<ws2tcpip.h> since IPv6 is no longer optional (was it ever?)

Replace <winsock.h> with <winsock2.h> + <ws2tcpip.h>
(ala libcurl since IPv6 is not optional now).

we really have no use for reverse lookups of the address.

I truly hope these are the last reverse lookups we had lingering in the
code!

version of libcurl with different Windows versions. Current version of
libcurl imports SSPI functions from secur32.dll. However, under Windows NT
4.0 these functions are located in security.dll, under Windows 9x - in
secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll
just forwards calls to secur32.dll).

Dmitry's patch loads proper library dynamically depending on Windows
version. Function InitSecurityInterface() is used to obtain pointers to all
of SSPI function in one structure.

  Curl_ossl_connect(), the Curl_gtls_connect() function does not send the user
  certificate to the peer. In fact, it ignores the conn->data->set.cert field
  completely, it always uses the anonymous credentials. See

 1.9 Where do I buy commercial support for curl?
 1.10 How many are using curl?
 6.7 What are my obligations when using libcurl in my commerical apps?

Edited a few other paragraphs slightly.

The LDAP code in libcurl can't handle LDAP servers of LDAPv3 nor binary
attributes in LDAP objects. So, I made a quick patch to address these
problems.

The solution is simple: if we connect to an LDAP server, first try LDAPv3
(which is the preferred protocol as of now) and then fall back to LDAPv2.
In case of binary attributes, we first convert them to base64, just like the
openldap client does. It uses ldap_get_values_len() instead of
ldap_get_values() to be able to retrieve binary attributes correctly. I
defined the necessary LDAP macros in lib/ldap.c to be able to compile
libcurl without the presence of libldap

(http://curl.haxx.se/bug/view.cgi?id=1338648) which really is more of a
feature request, but anyway. It pointed out that --max-redirs did not allow
it to be set to 0, which then would return an error code on the first
Location: found. Based on Nis' patch, now libcurl supports CURLOPT_MAXREDIRS
set to 0, or -1 for infinity. Added test case 274 to verify.

(http://curl.haxx.se/bug/view.cgi?id=1337723) that curl could not upload
binary data from stdin on Windows if the data contained control-Z (hex 1a)
since that is treated as end-of-file when read in text mode. Gisle Vanem
pointed out the fix, and I made both -T and --data-binary take advantage of
it.
