Just as a heads-up: There is a PR by Jessica Clarke now [1] which gets rid of
this
architecture-specific #ifdef. I think this is a good approach as it gets rid of
one
of your complaining points.
I have already verified that these changes don't break on 32-bit PowerPC,
64-bit SPARC
and, of course, M68k.
Thanks,
