DJGPP was my entrance to the world beyond 64kb in DOS. What a wonderful times :)
Imagine there still being a real world use case for a modern dos compiler :O (except for fun like this)
Woha! I didn’t know DJGPP was still alive. At some point in my life - before MinGW32 was a thing - I used an unholy combination of DJGPP + some open source implementation of the Windows headers + a tweaked linker (I can’t even remember where I got that from) to write Win32 programs. The surprising thing was that it worked just fine, other than missing a decent IDE.
