removed the prototype and made it include string.h instead

   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! :-(
