added hint to compile with SSPI with MSVC6 without PSDK.

it now will read the full data sent from servers. The SOCKS-related code was
also moved to the new lib/socks.c source file.

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

USE_WINDOWS_SSPI on Windows, and then libcurl will be built to use the native
way to do NTLM. SSPI also allows libcurl to pass on the current user and its

Renamed import lib to "libcurl_imp.lib".
Some cleanup and making it more readable.

Changes for removing libcurl.def file on Win32.
Added "CURL_EXTERN" to memdebug.h functions.
Cleaned up Makefile.vc6.

might be done differently in the future.
