It is easy to create example when simple strtok() is not sufficient
even without threads. One may want to split into tokens several
strings (take first token from the first string, then first from
the second, second and following tokens from both source strings
in the same way).

In that case strtok(s1, s2) will not work properly. With it one must
extract all tokens from the first string and only after that strtok
can be used for splitting another string.

So I think that we may need also strtok_r() for DJGPP
