     Jaromil, I agree with one of your other posts in which you say that 
changing optimisation options often reveals a bug in the source. But for 
the argument above, well... I'm not sure 90% of the millions of packages 
have been compiled with -O3.


     I remember, sometimes in the 80's, when Microware shipped their OS9 
with their new ANSI C compiler, I had found a bug in the compiler, 
caused by some level of optimisation - it could be demonstrated with an 
~5 lines example.
