Bug in ANSI C??

Unfortunately, the wording also appears to allow indeterminate results from
strcmp("aX", "a") where X is a high-bit character... which is WRONG!  The
lexical ordering of those two strings is well-defined regardless of char
signedness or collating sequence; allowing implementation-defined results
here makes strcmp almost useless in high-bit environments.
