Hi, I have no idea what I am doing so I just tried your commands as is. Here
is the output:

grep YYPRINT c-*.c -n -A 5
146:#define YYPRINT(FILE, TYPE, VALUE) c_print_token (FILE, TYPE, VALUE)
147-#line 148 "c-exp.c"
148-#define INT 257
149-#define FLOAT 258
150-#define DECFLOAT 259
151-#define STRING 260
4233:/* This is called via the YYPRINT macro when parser debugging is
4234-   enabled.  It prints a token's value.  */
4235-
4236-static void
4237-c_print_token (FILE *file, int type, YYSTYPE value)
4238-{
user:/tmp/insight-cvs/insight/gdb$ 

head c-exp.c 
#include <stdlib.h>
#include <string.h>
#define YYBYACC 1
#define YYMAJOR 1
#define YYMINOR 9
#define YYLEX yylex()

#define yyclearin (yychar=(YYEMPTY))

#define YYRECOVERING() (yyerrflag!=0)

I don't see that YYPRINT is used anywhere else in c-exp.c

Does the following suggest this isn't going to be used in a normal build?

/* This is called via the YYPRINT macro when parser debugging is
   enabled.  It prints a token's value.  */

static void
c_print_token (FILE *file, int type, YYSTYPE value)
{
  switch (type)
    {
    case INT:
      fprintf (file, "typed_val_int<%s, %s>",
	       TYPE_SAFE_NAME (value.typed_val_int.type),

Thanks,
