What is the FORECAST_LIST type?
/**
* gweather_info_get_forecast_list:
* @info: a #GWeatherInfo
*
* Returns: (transfer none) (element-type GWeather.Info): list
* of GWeatherInfo* objects for the forecast.
* The list is owned by the 'info' object thus is alive as long
* as the 'info'. This list is filled only when requested with
* type FORECAST_LIST and if available for given location.
* The 'update' property is the date/time when the forecast info
* is used for.

But FORECAST_LIST is never defined (maybe that's the providers mask now?)
