### Describe the bug, including details regarding any error messages, version, and platform. See https://github.com/apache/arrow/actions/runs/8849047421/job/24301450969#step:12:83 for example (on main). ``` g++ -std=gnu++17 -I"C:/R/include" -DNDEBUG -I../windows/arrow-16.0.0.9000/include -DARROW_STATIC -DPARQUET_STATIC -DARROW_DS_STATIC -DARROW_ACERO_STATIC -DARROW_R_WITH_PARQUET -DARROW_R_WITH_ACERO -DARROW_R_WITH_DATASET -DARROW_R_WITH_JSON -DARROW_R_WITH_S3 -DARROW_R_WITH_GCS -Werror -I'D:/a/_temp/Library/cpp11/include' -I"C:/rtools44/x86_64-w64-mingw32.static.posix/include" -O2 -Wall -mfpmath=sse -msse2 -mstackrealign -c extension-impl.cpp -o extension-impl.o In file included from ../windows/arrow-16.0.0.9000/include/arrow/scalar.h:32, from ../windows/arrow-16.0.0.9000/include/arrow/datum.h:29, from ../windows/arrow-16.0.0.9000/include/arrow/compute/api_aggregate.h:26, from ../windows/arrow-16.0.0.9000/include/arrow/acero/options.h:28, from ./arrow_types.h:38, from extension-impl.cpp:18: ../windows/arrow-16.0.0.9000/include/arrow/extension_type.h:53:15: error: 'virtual std::string arrow::ExtensionType::ToString(bool) const' was hidden [-Werror=overloaded-virtual=] 53 | std::string ToString(bool show_metadata = false) const override; | ^~~~~~~~ In file included from extension-impl.cpp:26: ./extension.h:55:15: note: by 'std::string RExtensionType::ToString() const' 55 | std::string ToString() const; | ^~~~~~~~ ``` I'm guessing that RTools 4.4 ships with a newer compiler/toolchain and this is throwing the warning (turned into an error by `-Werror`). Note `C:/rtools44/` in the include paths. FYI @assignUser ### Component(s) Continuous Integration, R -- This is an automated message from the Apache Git Service.
