History of m68k ABI and `-malign-int'?

Andreas, Jeff,

The documentation for `-malign-int' on m68k hints that 16-bit int
alignment was the prominent alignment chosen by m68k ABI's of the era.

Why is 16-bit int alignment the default for m68k in gcc?

Which ABIs influenced this decision?

Should Coldfire targets default to 16 or 32-bit int alignment?

Cheers,
Carlos.
