Hi All,

I would like to know of existing systems where CHAR_BIT of <climits>
is not equal to 8. I am particular interested in prevalent systems.

Technically, my code is mostly portable, but only within a particular
machine. Innter-machine interaction (serialization for example), there
will be problems for those machines where CHAR_BIT != 8.

Yes, yes, I know, it enough effort, I can rewrite my code to eliminate
any potential compatibilities even then, but still, it helps to
know. :)

Probably a lot of CPU's have CHAR_BIT = 16 or 32. If you plan for
porting your code to e.g. cellphones and PDAs you are likely to get
into troubles (I've programmed on a PDA that had CHAR_BIT = 16).
If you turn into more exotic architectures you are of course even more
likely to experience problems.
