DJGPP (DJ's GNU Programming Platform) is a 32-bit C/C+/ObjC/ObjC++/Ada/Fortran development suite for 386+ PCs that runs under DOS or compatibles. It is guided by DJ Delorie, who started the project in 1989. It is a port of the popular gcc compiler, as well as many other GNU utilities such as bash, find, tar, ls, mv, awk, sed, and ld to DOS DPMI (DOS Protected Mode Interface). It uses a flat memory model, where code and data segments are coincident. Additional segments can be accessed indirectly.
