Do I understand correctly that you see similar warnings on GNU/Linux
systems?  If so, perhaps some README should tell that this warning is
unavoidable and expected, and should be disregarded.

Anyway, on platforms that use pre-cooked config.h files, like
configh.DOS, perhaps we could define a macro there that would avoid
the warning (since the precise types of the relevant data types is
known in advance), and then the other *.h files could use #ifndef?
