When I did 1 << 24 I got a warning (at least on the mainline on a cross to avr) about 24 being greater
than the size of int so it was going to be 0. Again in real terms there is something on here but I really
doubt it is a regression and you did not use -mint8 for the 3.3 build and not for the 3.4 build.
