 /* Parse S into tokens separated by characters in DELIM.
    If S is NULL, the saved pointer in SAVE_PTR is used as
    the next starting point.  For example:
-       char s[] = "-abc-=-def";
-       char *sp;
-       x = strtok_r(s, "-", &sp);      // x = "abc", sp = "=-def"

-   Caveat: It modifies the original string.
-   Caveat: These functions cannot be used on constant strings.
-   Caveat: The identity of the delimiting character is lost.
-   Caveat: It doesn't work with multibyte strings unless all of the delimiter
-           characters are ASCII characters < 0x80.
