DJGPP is a 32 bit protected mode compiler.
So it attaches to the executable code for a dos extender&DPMI support
like CWSDPMI and it kiks your kode into protected mode.
This takes some kilos...
But for a "hello world" program you don't need DPMI or 32bit code or
protected mode or whatever advantage DJGPP has.so a "hello world"
program is best made via pascal or turbo C.
The advantages Of 32bit DPMI code will show up on *real* projects.
