ISAs aren't always so simple these days; orginally a "word"
was a common measure for instruction, non-floating datum,
address, width of data bus, with of memory access, etc., but
now these often don't match each other so one is hard-put to
name a definite "word" size.
A C implementor might well choose "int" to be 32 bits even
on a machine where 64 bits would be more natural, in order
to ease importing of code written sloppily on a so-called
32-bit platform.
