Of course - you have to compile OpenSSL, using the Visual 
C++ commandline compiler - see txt file in the httrack 
src_win directory:

# Install cygwin (binaries, only perl and various tools, no 
need for gcc)

perl -I"C:\Program Files\cygwin\lib\perl5\5.6.1" Configure 
VC-WIN32
cd src
ms\do_ms
nmake -f ms\ntdll.mak

Librairies are being generated in 
C:\Dev\openssl\src\out32dll
