Aheam, I think vc6curlsrc.dsw is for building the curl executable. You probably
need to build with vc6libcurl.dsw. But where is .\lib\vc6libcurl.dsp that's
refered to in the *.dsw file? So the whole VC builds methods seems confusing
and "out-of-whack" with the FAQ. See:
  http://curl.haxx.se/docs/faq.html#Link_errors_when_building_libcur

Target: static lib. import lib for libcurl*.dll.
-----------------------------------------------------------
MSVC (release): libcurl.lib libcurl_imp.lib
MSVC (debug): libcurld.lib libcurld_imp.lib

But if you see in 'winbuild/MakefileBuild.vc', the import-lib for a release build
is named 'libcurl.lib'. And the import-lib for a debug-build is named
'libcurl_debug.lib'. Don't know when that happened. Anyway, the winbuild-dir
seems most up-to-date. Try that build-method instead.

Because the linker expects to see import symbols and the 'libcurl.lib' you provided
didn't have any. Depending on how you build the curl-lib, add the correctly named
import library. Hope you know the difference between a static library and an import
library (?).
