The djgpp system elected to implement a library of calls to the DPMI
(Dos Protected Mode) interface in Windows, and this allows them to
port Unix applications that call on /dev/mem.  However, such ports
are really partial rewrites of the original source code.

It would be a whole lot more elegant to implement /dev/mem in the cygwin.dll
so that Unix programs that call file open, close, and seek functions that
involve /dev/mem will work properly.   And, that would serve to distinguish
the cygnus.com approach from the djgpp approach.
