Description

When using pyarrow interface from a c++ library one will get the following compiler warning:

warning: 'unwrap_table' has C-linkage specified, but returns user-defined type 'arrow::Status' which is incompatible with C [-Wreturn-type-c-linkage]
ARROW_EXPORT Status unwrap_table(PyObject* table, std::shared_ptr<Table>* out);

This is due to a Cython artifact.
