libtransmission/announcer.cc:929:8: warning: type ‘struct announce_data’ violates the C++ One Definition Rule [-Wodr]
  929 | struct announce_data
      |        ^
libtransmission/announcer-http.cc:299:8: note: a different type is defined in another translation unit
  299 | struct announce_data
      |        ^
libtransmission/announcer.cc:931:15: note: the first difference of corresponding definitions is field ‘tier_id’
  931 |     int const tier_id;
      |               ^
libtransmission/announcer-http.cc:301:22: note: a field with different name is defined in another translation unit
