It couldn't work. MinGW generates Win32 exe's, so you can't call 
interruptions.
If you really feel like using interruptions, and not the Win32 API, 
download DJGPP, compile your program with it, and run your program in 
DOS environment (aka: not on Win NT/2k/XP).
Remember that if you're programming in a real operating system, you 
should use system calls, not interruptions.
