Research direction

Reproduce the issue on macOS High Sierra using the shown test.h header and bindgen --whitelist-type Foo test.h. Inspect the generated Rust bindings, focusing on why __darwin_size_t is retained while other Darwin types are filtered. Done means the Foo binding remains available without any unwhitelisted Darwin internals.
