willows TWIN
The Willows TWIN libraries are both a set of native platform libraries and an emulator program to emulate the Microsoft Win32 API. The emulator program allows executing Windows binary programs on supported Unix platforms, on native Intel x86 processors, and through the built-in instruction set interpreter. The native libraries allow programmers to natively build Win32 and MFC applications from source code.
