Joseph correctly mentioned that iff AVR would define __int24 using INT_N in avr-modes.def the issue would have been mitigated as well (that's a comparatively "modern" way of registering additional integer types). So it's really also a target issue. I'm not planning to backport this frontend change given a more targeted fix would be available.
