I've just added support for the huge memory model via the -huge option.

It'll let you compile 32-bit code for DOS. Ints and pointers are 32-bit.
Pointers are 32-bit physical addresses.

No need to mess with segments. And you can have arrays larger than 64KB! :)

In this model the stack is limited to 64KB and the cumulative size of local 
variables is limited to 32KB (this is a per-function limit).
Individual functions are limited to 32KB of code size.
These limitations should not pose problems normally.

This is how you can (re)compile Smaller C using the huge memory model 
(provided you have a 32-bit Smaller C already, compiled with gcc/DJGPP, Open 
Watcom C/C++ for Windows/DOS4G, etc):

smlrc -huge -no-externs lbdos.c lbdos.asm
smlrc -huge -no-externs -label 1001 smlrc.c smlrc.asm
nasm -f bin smlrchg.asm -o smlrchg.exe

Enjoy and a happy New Year!
