Yes, I see libjpeg here:
https://github.com/winlibs/libjpeg/blob/master/readme.dos

and here:
https://github.com/mitsuba-renderer/libjpeg

specific DJGPP compile makefile
makefile.dj jconfig.dj MS-DOS, DJGPP (Delorie's port of GNU C)

Not sure which of these two to attempt to compile. The second one seems more "current" for libjpg.
