// AtkTableCell was introduced in ATK 2.12. Ubuntu Trusty has ATK 2.10.

// However, we also need runtime checks in case the version we are building
// against is newer than the runtime version. To prevent a runtime error, we
// check that we have a version of ATK that supports AtkTableCell. If we do,
// we dynamically load the symbol; if we don't, the interface is absent from
// the accessible object and its methods will not be exposed or callable.
// The definitions below ensure we have no missing symbols. Note that in
// environments where we have ATK > 2.12, the definitions of AtkTableCell and
// AtkTableCellIface below are overridden by the runtime version.
