"outwith" => "outside"?

If it's a problem for any fully conforming versions of C, it's a problem
my code should, ideally, be able to deal with properly, regardless of
whether there's other fully conforming versions where it is not.

What I'm allowed to assume for the project I'm working on, and what I'm
willing to assume in general, are two very different things.

Even on this particular project, my code actually relies very little
upon that particular assumption. That's possible primarily because one
of the third-party libraries I'm required to use hides a lot of the
implementation-specific details within it's own code. Because there's no
requirement that my code operate on non-POSIX platforms, I could not get
permission to spend any significant amount of time making sure that it
did; but if that requirement were changed, I doubt that my own code
would require many fixes.

A very small portion of my code relies upon the POSIX guarantee that
CHAR_BITS==8; most of it is carefully written to avoid making that
assumption. Those five programs rely upon that guarantee in order to
parse some data structures. If I could no longer rely upon POSIX, that
would be the most difficult part to fix.
