How to compile OpenSSL version 1.0.2 using Borland C++ Builder 6 on Windows XP SP3?

Question

I have found that the documentation for OpenSSL 1.0.2 suggests compiling it using Borland C++Builder 5. However, when I attempted to compile it using Borland C++Builder 6, I encountered the following error message:
