        * libc/include/limits.h: Define LLONG_MIN, LLONG_MAX and ULLONG_MAX
        for C++11 too.
        * libc/include/stdlib.h: Define struct lldiv_t, _Exit, atoll, llabs
        and lldiv for C99 and C++11.  Move wcstold to wchar.h.
        * libc/include/wchar.h: Define WCHAR_MIN and WCHAR_MAX according to
        __WCHAR_UNSIGNED__ if it is provided, and correct the limit when
        unsigned (to 32 all-1 bits, not 31).  Define FILE as in stdio.h.
        Move wcstold from stdlib.h here.
