I'm out of my depth here, so please take what I say with a grain of salt
-- but my impression is that we never followed the published standards
...which said: "Align ints to a word boundary. This breaks compatibility
with the published ABI's for structures containing ints, but produces
faster code on cpus with 32-bit busses (020, 030, 040, 060, CPU32+,
ColdFire). It's required for ColdFire cpus without a misalignment
The de facto ABI as defined by the toolchain itself may be more relevant
if the only published standards are obsolete.
