Win32s x 1.x

Win32s (Win32 subset) was an API layer for Windows 3.1 and Windows for Workgroups that allowed some Win32 applications that compiled with the subset of Windows NT API functions supported through 32->16 bit thunks. Certain functions such as threading and OpenGL were not supported. As Windows 3.1 was cooperatively multi-tasked, so are Win32s applications on 3.1 and memory space is still shared.
