given that the dynamic executable is 2816 bytes, the static one could be 
smaller, however it is way bigger. In fact it seems to me (but I don't
rerally know a lot about those things, I was only saying something I saw
elsewhere) that it is way too bigger for that difference to be explained by 
static linking, there is something else happening there. 

In any case I stand corrected.
