How to attach source code in a debug build(Win32 Visual C++)?

[JC Yang]

Hi, I'm new to openssl. I've just compiled openssl with Visual C++ 2008,
I've read the installation guide and added the debug command in the
mk1mf.plline in do_masm.bat, but I found that there's no source code
information
included in the build. I'd like to know how can I attach the source code in
the debug build for debug's sake?
Thanks.
