Doesn't ANSI C requires toupper to leave nonlowercase chars unchanged? This is not the case with gcc on our (sun) system as it seem to use ctype.h as supplied by sun. G++ have the same problem even though it has it's own ctype.h. Is this a bug or has ANSI C changed since Harbison&Steele was printed?
