ANSI C guarantees that char is 1 byte (more precisely that "sizeof (char)" == 1).
That's also what the C++ ARM says (which I have to hand). Unfortunately,
"a byte is undefined by the language except in terms of sizeof; sizeof(char) is 1." [sec. 5.3.2]
Maybe ANSI C is different?
1990 ANSI/ISO C requires chars to be at least 8 bits wide in section 5.2.4.2.1. This extends to ANSI/ISO C++, which cites ISO C for its definition of <limits.h>. Haven't got C'99 handy, but it'll be a similar story - char is *at least* 8 bits wide. Hope that satisfies the pedants. Pat.
