230KB is about right for GCC 3.x.  The rest (the stuff stripped by 
`strip') is debug and symbolic info that is never loaded into memory when 
the program runs, it is only there for when you need to debug the 
program, or symify the crash traceback.

Welcome to C++, a monstrously large language, where even to say hello you 
need a lot of baggage.  If that bothers you (I don't think it should), 
don't use C++.

This has nothing to do with 32-bit vs 16-bit programs.  It has everything 
to do with the bloat in C++ classes used to print formatted messages.  
The fact that C programs, which also run in 32-bit protected mode, are so 
much smaller is the proof of this simple fact.
