+Subject: [PATCH] fix: Resolve API incompatiblities on FreeBSD hosts
+
+FreeBSD's `libutil` library defines `pw_init` and `pw_deinit` functions,
+conflicting with the PipeWire API `pw_init` and `pw_deinit` functions.
+
+To resolve the conflict, the PipeWire package in FreeBSD's ports
+patches the function definitions, renaming `pw_init` to `pipewire_init`
+and renaming `pw_deinit` to `pipewire_deinit`.
+
+As a result, the expected `pw_init` and `pw_deinit` functions are not
+generated on FreeBSD (and probably other BSDs).
+
+Since Rust supports namespaces, we can manually define `pw_init` and
+`pw_deinit` aliases and there are not conflicts with any other libraries.
+
+Notes:
+* `pipewire-sys/build.rs`
+  Update add the `pipewire_*` pattern to the allow list, so that the aliases are picked up by bindgen
+* `pipewire-sys/src/lib.rs`
+  Adds aliases to for `pipewire_init` and `pipewire_deinit` to `pw_init` and `pw_deinit` respectively.
