Does MSW 3.0 include a DOS extender? How do I develop protected mode
applications to run under 3.0?  I assume I would need a compiler and
linker that generate code for the extender.  Did Microsoft announce any
development tools for this purpose?

A related note.  Quarterdeck had a display in the Xhibition, with demos
of their X-Windows implementation for MS-DOS.  They are able to run
both X server and clients in 286 and 386 DOS machines, with
applications  running under a variety of DOS extenders. It runs under
Deskview, allowing users to mix-and-match real, protected mode  DOS and
X-Windows applications.  They claimed it wouldn't require much hardware
(demo included a 286-laptop).  Quarterdeck's approach offers PC
developer the possibility of writing code portable to a variety of
machines.

Question: How does this impact Windows 3.0?
