char signed or unsigned

[Joe Van Dyk]

char s;

Is it really implementation-defined as to whether s is an unsigned or
signed char?

Apparently so. 3.9.1-1.

BTW, it only means that the range of 's' is that of either 'signed char' or
'unsigned char'. But the type of 's' is still just 'char' and 'char' still
remains an independent type, different (as an independent type) from both
'signed char' and 'unsigned char'.
