Hi Arkady,

That is quite nice of the OpenWatcom 1.6 DOS target :-).
Even though their printf is not really "lightweight" ;-).

That is indeed a problem. Processing of 32 bit values can
be done in much more elegant (and compact/optimized) way
when you can actually use 32 bit registers. Even if your
program is running in a 16 bit real mode memory model.
The memory model is just about pointers, while 32 bit
values are useful for many things. Japheth also mentioned
bad pointer handling optimizations in OpenWatcom, but
thats another issue.
