I think the point is that if a machine/ABI comes along with
sizeof(int) > 4 (e.g. if there's a significant penalty for working
with anything < 64-bit), Linux might consider supporting that. Whereas
if someone points to their microcontroller or ancient 286 with
sizeof(int) == 2, the answer would be, "Here's a nickel, kid -- get a
real computer".
