Ok, sorry, forgot all the junk I wrote.

make CC="gcc -falign-functions=16" install

and "running" was 1215 ticks, with 8 it's again 1315

(allway 16 byte alignment)
speed: function+loops (1349 ticks) < function (1215) < function+jump
(1207) <function+jump+label (1194) <function+jump+label+loops (1173)

compare it to the values in the other mail

At least the function alignment seem to be good on a Athlon, but I don't
know about other system, but I think that it also won't be bad.
