Re: [BUG] wprintf(L"%s", str) expects str to be wide

Corinna:
     Are we looking at the same place?  Lines 1200-1217 of 
libc/stdio/vfwprintf.c version 1.10 are what I looked at.  I only see wide 
functions there.  I'll quote from line 1199 to get the #endif:
#endif /* _MB_CAPABLE */
                        if (prec >= 0) {
                                /*
                                 * can't use wcslen; can only look for the
                                 * NUL in the first `prec' characters, and
                                 * strlen () will go further.
                                 */
                                wchar_t *p = wmemchr (cp, L'\0', prec);

                                if (p != NULL) {
                                        size = p - cp;
                                        if (size > prec)
                                                size = prec;
                                } else
                                        size = prec;
                        } else
                                size = wcslen (cp);

                        break;
