actually...
as you don't need anything but the winhttp5.dll but it's probably faster for you to download the whole package from US...

and when read from the BBChecker version 1.5 Readme, it really had winhttp allright.
winhttp is at http://msdn.microsoft.com/downloads/default.asp?URL=/code/sample.asp?url=/MSDN-FILES/027/001/655/msdncompositedoc.xml
