As often, Eli Zaretskii <eliz AT is DOT elta DOT co DOT il> gave me the right answer:

I want to make a bootable floppy which contains all necessary files to
run the program. I have djgpp installed on different drives in
different computers (development platforms), but the floppy should run
on computers without djgpp (and without dos). 

The absence of protection makes dos (djgpp) an ideal development
platform for hardware diagnostics.
