removed the prototype and made it include string.h instead

char *Curl_strtok_r(char *s, const char *delim, char **last);

#define strtok_r Curl_strtok_r

#else

extern char *strtok_r(char *s1, const char *s2, char **lasts);

#include <string.h>

/* If your system, such as Solaris 2.7, lacks the strtok_r() prototype in

   string.h, then you'll face a bunch of warnings on all instances

   where strtok_r() is used.

   There's not much we can do about it. Adding a prototype here screws

   everything up on other platforms! :-(
