Flutterby™! : DJGPP and DOS programming

I got a request for a quick-and-dirty program to display some text in a specific graphic mode and a specific screen location (some really poor design engineering in a computer controlled sign). So, instead of whipping out the dusty copies of Watcom C/C++ or Turbo C++ and MetaGraphics libraries, I decided to give DJGPP a whirl. Low and behold DJGPP, the DOS port of the GNU C/C++ compiler, is feature rich, has a very thorough game/graphics library called Allegro, and even sports an IDE that I would died for back at Signal Data with Dan.
