Please (as always) post a test program, because it works file for me  
with 2.0.4-rc3.

Always post a compilable program which demonstrates the problem if  
you want bugs to be fixed, preferably in the bug tracker at http://

Definitely final for 2.0.4-rc3. Make sure you also use -CX -XX to  
turn on smartlinking.

It may become bigger or smaller in the future depending on a number  
of factors, including but not limited to optimizer improvements,  
(smart)linking improvements, routines added to the system unit which  
are referenced from the initialization section, effort required to  
investigate in detail why things became bigger vs the impact this has  
for most people, the fact whether someone who actually cares about  
executable file size performs said investigations, and the phase of  
the moon.
