/* 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.
+ The COFF image is loaded in memory without the stub attached, so
+ all offsets are relative to the beginning of the image, not the
+ actual file. We handle this in bfd by setting bfd->origin to where
+ the COFF image starts. */
- To be compatible with any existing executables I have fixed this
- here and NOT in the DJGPP startup code.
