  |  
  |  The lines to move are:
  |  
  |  static int nstored = 0;
  |  static char **storage = 0;
  |  
  |  This will allow the compile to proceed.

That mostly worked. I had to move that static declarations with the
#include-s

%{
#include <stdlib.h>
#include <string.h>
#include "local_proto.h"

static int nstored = 0;
static char **storage = 0;
%}

And then leave the #include "lex.yy.c" where it was.  It then compiled
fine.  Now onto the next error...
