In many cases int is slower now than long -- which violates the notion
of int from K&R days.

That's a designers's choice, I think.  It is possible to add 32-bit
instructions which should be as fast (or possibly faster) than
64-bit instructions, as AMD64 and ARM have shown.

And having a smaller memory footprint is also beneficial, especially
for caches.

(Plus, there are FORTRAN's storage association rules, but these should
be less used by now.  But for a 64-bit integer, they pretty much would
require a 64-bit REAL and a 128-bit DOUBLE PRECISION).
