There is also a simple fix for the existing 2.03/2.04 default malloc - in the free() code remove the block merging stuff. It is O(N**2) or O(N**3). When memory was tight it might have made sense with a better implementation (to avoid paging to hard disk) - but just remove that code today and I doubt anyone will notice (other than huge speed increases freeing lots of blocks). But the other issue here is Microsoft has pushed 64-bit default distributions so hard that anyone with a system newer than XP probably cannot run the 16-bit DOS interfaced DJGPP.
