/* This file handles now also stubbed coff images. The stub is a small
DOS executable program before the coff image to load it in memory
and execute it. This is needed, because DOS cannot run coff files.
All the functions below are called by the corresponding functions
from coffswap.h.
The only thing what they do is to adjust the information stored in
the COFF file which are offset into the file.
This is needed, because DJGPP uses a very special way to load and run
the coff image. It loads the image in memory and assumes then, that the
image had no stub by using the filepointers as pointers in the coff
image and NOT in the file.
To be compatible with any existing executables I have fixed this
here and NOT in the DJGPP startup code.
