I compiled Quake without needing to change it and worked quite nice (I used
it to play network deathmatch cheating ;-))))
But I used something like djgpp 2.01 and never tried with 2.03.
About the memory: They just allocate all the memory in one shot and then
administrate it with a special allocation routine. I think the main purpose
of it is just debugging. Each allocated block have extra information, like
object type.
Is amazing to see how the programs wastes resources in most of the code. They
knew very well what to optimize and just optimized it.
