- Win32, OS/2 & Posix are the only subsystems in Windows NT - the Win16
- and MS-Dos support are virtual machines written to use the Win32
- API (plus some helper functions) - they're not subsystems in of
- themselves
-
- POSIX compatibility and upwards compatibility from Windows are
- mutually exclusive options, and likewise POSIX & OS/2
- compatibility - OS/2 & Windows co-compatibility is the closest
- to being possible. SO we could have produced a new API
- incompatible with any of the above, or choose the route we have
- and keep the US Govt happy with true POSIX compatibility, and
- serve OS/2 & Windows customers with true compatibility
