zbar recipe build fail

### Logs

```
In file included from decoder.c:24:
./zbarmodule.h:42:5: error: unknown type name 'PyIntObject'; did you mean 'PySetObject'?
PyIntObject val; /* integer value is super type */
^~~~~~~~~~~
```

Start by reproducing the zbar recipe build and inspect decoder.c and zbarmodule.h around the reported declaration. Done means the zbar recipe builds past this compiler error.
