/* ffestr_first -- Look up the first names in a statement

   ffestrFirst kw;
   ffelexToken t;
   kw = ffestr_first(t);

   Returns FFESTR_firstNone if no matches, else FFESTR_firstXYZ if the
   NAME or NAMES token matches XYZ.  t must be a NAME or NAMES token or this
   routine will crash.

   This routine's code is actually written by a utility called FINI, itself
   written specifically for the Gnu Fortran project.  FINI takes an input
   file, in this case "ffe_first.fini", consisting primarily of a
   list of statements (ASSIGN, IF, DO, DOWHILE), and outputs a C file,
   "str-1t.j", that contains the definition of the
   ffestr_first function.  We #include that file here.
