I'd say C90 (6.1.2.5) "Even if the implementation defines two or more
basic types to have the same representation, they are nevertheless
different types." is perfectly clear. In C99 the footnote
35)CHAR_MIN, defined in <limits.h>, will have one of the
values 0 or SCHAR_MIN, and this can be used to
distinguish the two options. Irrespective of the choice
made, char is a separate type from the other two and is
not compatible with either.
is added.
