Looking at the x32 case, I have to say that "long" in general looks
horrible. Especially when we have things like

  typedef long long __kernel_long_t;

(and __long really wouldn't look any nicer). Any sane person would go
"Eww" at looking at that - we're using 'long long' to typedef a type
that is named 'long'.

It would make much more sense to use "__word" for reasons like that.
But I really don't think that works well in a x86 context.

Other ideas? Maybe "__wordsize" would be less associated with x86 16-bit words?
