You will get the same .exe size, I think.  The bloat is not caused by the
compiler, it's because the startup code calls library functions that are
added to your code.  If you want to avoid linking those functions, you
will have to write your own startup code. 

I fail to understand why would somebody be so excited about extra 20KB to 
go to such lengths.  (If your program is much larger, use -s switch when 
you compile, for starters.  See section 8.15 of the DJGPP FAQ list.)

No, DEBUG doesn't understand the AT&T assembly syntax emitted by GCC, so 
you can't.

You won't see any difference by assemblying the code emitted by GCC,
because you will assemble the same code that GCC passes to the assembler. 
You will have to rewrite code in hand-optimized assembly to see any
difference at all.
