Describe the bug, including details regarding any error messages, version, and platform.

Compiling Arrow 15.0.0 with Clang 19 results in error: arithmetic on a pointer to an incomplete type 'FileInfo' in FileSystemDatasetFactory class. Can't test latest Arrow right now.

A complementary issue to https://github.com/llvm/llvm-project/issues/102293, more info there.
