C++ library missing?

[danaskinner]

I am trying to recompile someone else's code. He used the following line:
#include <UI_WIN.HPP> // Zinc application library
I have never seen this before. Should it be a part of the Borland C++ version 4.5 compiler that I am using. Can I download this file anywhere?

Please help. Any suggestions or comments are welcome.

Doing a quick google search it looks like it is a header for the Zinc application library. You probably need the headers and libs from Zinc to be able to recompile this.
