We also have things like the following in packet-ypserv.c:
  static const value_string ypstat[] =
  {
          {       1,      "YP_TRUE"       },
          {       2,      "YP_NOMORE"     },
          {       0,      "YP_FALSE"      },
          {       -1,     "YP_NOMAP"      },
          {       -2,     "YP_NODOM"      },
          {       -3,     "YP_NOKEY"      },
	  ...

  static const value_string xfrstat[] =
  {
          {       1,      "YPXFR_SUCC"    },
          {       2,      "YPXFR_AGE"     },
          {       -1,     "YPXFR_NOMAP"   },
          {       -2,     "YPXFR_NODOM"   },
	  ...

when epan/value_string.h defines value_string as:
  typedef struct _value_string {
    guint32  value;
    gchar   *strptr;
  } value_string;
