Oh, so ptrdiff_t joined uintptr_t in being 64-bit
on APE architectures, while size_t is still 32-bit.
It seems plausible, as addresses are generally 64-bit,
so diffs might also be bigger than 32-bit, at least
in the future.

Still, it’s interesting which kinds of "assumptions"
Posix code sometimes makes, that breaks depending on
the size of this type? I mean an application that uses
these quite specific types, in contrast to 'ordinary
types' such as int*, long, long long etc., would really
pick the right type for the right situation, and it
would just work?

I am not questioning anything, I am just curious to
understand type sizes, and porting, better.
