That's true: a DJGPP program has a short 2KB stub loader prepended to
it. To the OS, that stub is the program; the COFF image is just data
which the OS knows nothing about. When the stub is invoked, it reads
the COFF information from the rest of the .exe file, sets up memory as
required by the sections in the image, then jumps to the start point
of the COFF image.
