That anyone's still selling? I don't, but there's a well-respected example that could reasonably be implemented that way: on the DEC-10 # define CHAR_BIT 9 # define UCHAR_MAX 511 # define CHAR_MAX 127 # define CHAR_MIN -128 would make perfect sense -- I don't see any need to support 9-bit chars here beyond the dubious proposition that broken code should work anyway. There is a requirement in C99 that unsigned char[N*sizeof(T)] be large enough to hold any T[N] value. Is there any requirement that N be the _smallest_ multiple of sizeof(T) large enough to hold a T[N]? I don't see it on a cursory search, nor why there should be one.
