I'm no expert on internationalization - as a US programmer I've never
had any need to worry about it. However, that question at least I can
answer:

C99 says, in effect, that the above expression is guaranteed to be true
if the implementation does not pre-define __STDC_MB_NEQ_WC__ (7.17p2).
6.10.8p1 seems to indicate that definition of the macro with a value of
1 is mandatory - but that might be an example of poor wording or a
misinterpretation on my part. It seems inconsistent with the "if" in 7.17p2.
