You wanted to have a compiler capable to generate programs working on any
x86 CPU, this one will. But there is no easy way to have more than 1MB on
8086/8088 system and access it. So you need either require at least 80386 or
deal with 8086/8088 limits. Choose what's of most importance to you.

Then stay with DJGPP and require 80386.

You may though allocate some space on the hard disk (a huge file, I guess)
and make a real-mode program for 8086/8088 that would use this file as
memory but this will be extremely slow even if you have caching because disk
access is more than on the order of magnitude slower than RAM.

Good Luck
