Except that optimization was turned on in this experiment :). I think we all 
agree that tcc is really nice to try a build (like automatic build after each 
commit in a project) or for programs where speed is not crucial, and that for 
production use gcc is the right candidate. And also tcc is able to run C code 
as a script :)
