True, it is only possible to run a true 32 bit app on a machine that has
a true 32 bit processor, such as a 386 or better :-)

It is possible to write a C compiler for real mode DOS that treats the
first meg of memory as a linear address space. I suspect, however, that
apps built with this compiler would run a factor of 4 or more slower.
You would suffer with *every* pointer operation. Functions like strcmp()
would be pig slow. I don't think there is much of a market for such a
beast.
