This was a fun read, and what is scary is how much of this memory is fresh as newly plucked fruits with uncounted boxes full of APIs that have long gone to dust sitting besides it.
Maybe one day it will come in handy again.
In case you don't know what djgpp is: http://www.delorie.com/
Also found this quote on the History of DJGPP page: DJGPP was born around 1989 (originally called djgcc), when Richard Stallman spoke at a meeting of the Northern New England Unix Users Group (NNEUUG) at Data General, where I then worked. I asked if the FSF ever planned on porting gcc to MS-DOS (I wanted to use it to write a 32-bit operating system for PCs), and he said it couldn't be done because gcc was too big and MS-DOS was a 16-bit operating system. Challenge in hand, I began.
I like his moxie.
