This relates to what I just said in another topic.  Discounting function
prototyping (ANSI proposed), actual arguments of type char, short, float,
and array are converted; therefore one should never declare formal arguments
of these types.  However, you are right -- the C language is supposed to
silently fix it for you by interpreting your "char" declaration as an "int".
Your compiler is broken.
