Check for viruses.  All or nearly all viruses don't understand the 
way djgpp programs are laid out in the file, and so can't infect them 
properly.  They just infect the bit of the file they do understand 
(the stub), overwriting part of the COFF image, and so when the stub 
tries to load the COFF image it fails, giving the above error.

See the DJGPP FAQ section 6.5 for details.
