In the file cffi-ecl.lisp of I find the equivalence table
(:char :byte "char") (:unsigned-char :unsigned-byte "unsigned char")
that associates, for the ECL port, a byte with the CFFI :char type. Is this intended per-specification? Why not using ECL's :char type, which might be more than one byte if the compiler and operating system expect so?

My guess is that we're using :byte instead of :char because ECL's :char converts C chars to Lisp characters, which is not what CFFI's :char is supposed to do. In any case, the C spec states that sizeof(char) == 1, does it not?
