I don't understand why I need to patch below to build this dissector, whereas the buildbots seem to be fine.

Without this patch I get:

packet-q708.c: In function `proto_register_q708':
packet-q708.c:11689: warning: dereferencing type-punned pointer will break strict-aliasing rules

This could be made to work if value_string_ext were re-ordered so that 'vals' was at the start...

typedef struct _value_string_ext {
  value_string_match_t match;
  guint length;                 /* length of the array */
  const value_string *vals;     /* the value string */
} value_string_ext;
