The original version came with Turbo Pascal 6, the C++ port came later.

So this is a modern port of the port. :)

Borland did the same with other frameworks OWL came first in Turbo Pascal for Windows 1.5, and many of C++ Builder tools are actually written in Delphi.

Anyway, Turbo Pascal 5.5 adoption of Object Pascal, followed by Turbo Vision on version 6, was my introduction to OOP, and it I was lucky have gone that path.

Got to learn OOP, and all the goodies that Turbo Vision offered as a framework in an environment like MS-DOS.
