/* simpletypes.h: basic string, boolean, etc., that we use in kpathsea.

   This is needed to avoid a loop between types.h and str-llist.h.
   Otherwise, types.h would have to be included before str-llist.h,
   because types.h itself also includes str-llist.h, and its following
   use of str_llist_type would not be defined.  So instead we have
   str-llist.h #include this, instead of the full types.h.  All follows
   from types.h including nearly everything, so that MetaPost can be a
   threaded library.
