DJGPP is a complete 32-bit C/C development system for Intel 80386 (and higher) PCs running DOS. It includes ports of many GNU development utilities.

The development tools require a 80386 or newer computer to run, as do the programs they produce. In most cases, the programs it produces can be sold commercially without license or royalties.

It is fun to port industry-strength applications to MS-DOS and have them running seamlessly on top of a 16-bit "toy operating system". It is fun to see how these applications change the way your system looks and feels, to a point that you can almost think it is a Unix box.

It is fun to have all the source code, down to the darkest corners of the library internals, free for reading and hacking. It is fun to be able to find and fix bugs no matter whether they occurred in the application code, in the library, or in the compiler. And it is fun to discuss all these matters with other users and developers all over the world, and to join forces to make the free software better and more powerful.
