In which case, it's yet another section that could really do with a
complete rewrite from scratch to bring it more up to date.
That seems to be pretty common...
Barring that, I might just strengthen the note about how word length is
sensitive to the hardware you're dealing with, and it may be necessary
to refer to platform specific documentation for these things.
That also seems to be pretty common...
