  icaltzutil_fetch_timezone now creates VTIMEZONE components using
  RRULEs rather than expanding out every year (if
  USE_INTEROPERATIVE_VTIMEZONES was off) or using a single time zone
  back to 1970 (if it was one).

  This creates more accurate time zones that are compatible with dates
  whose time zones have since transitioned to a different offset (such
  as a date in America/New_York in 1980).  Removed
  icaltzutil_set_exact_vtimezones_support and
  icaltzutil_get_exact_vtimezones_support.  Removed
  USE_INTEROPERABLE_VTIMEZONES.

Add missing USE_GNOME=introspection:build
