Are you talking about time64 related alignment here, or in general?
Isn't the alignment is dictated by the 68k SysV ABI? Does this mean that
Debian and another X 68k distro (say, embedded builds), that decides not
to go ahead with this change not to be ABI compatible?
Doesn't this need compiler changes as well? (Example: natural alignment of
the stack on m68k (non-CF) is still two, enforced by the CPU behavior, and
needs changes to stackframe management if you want to change this to 4).
