Hi, I just noticed a couple of things in strcasestr.c which cause warnings on ${OTHER_OS}, but still apply to us: char * strcasestr(s, find) const char *s, *find; { char c, sc; size_t len; if ((c = *find++) != 0) { c = tolower((unsigned char)c); len = strlen(find); do { do { if ((sc = *s++) == 0) return (NULL); } while ((char)tolower((unsigned char)sc) != c); } while (strncasecmp(s, find, len) != 0); s--; } return ((char *)s); } We have two calls to tolower(); the first doesn't cast the result at all, the second one casts it to char. Shouldn't the first one be changed also? Actually, my first feeling was to change both to unsigned char, but I'm sure somebody could go to great lenghts to explain to me how the code as it stands is carefully crafted to work whether chars are signed or unsigned....
