Most of these are places where we failed to include a header file and simply never got an error about this. The fix is to include the header file. Most other cases are functions that should have been marked `static` but were not. Finding all of these was a main motivation for me enabling the warning despite how much work it is. One complicating factor was that we weren't including the `handle.h` for all the state-based handler functions. While this isn't a tiny amount of code, it is just declarations and doesn't add any extra dependencies. It also lets us have the checking for which functions need to be `static` and which don't. For the `parse` library I had to add the `handle.h` header as well, I tried to match the design of it in `check`. I have also had to work around a bug in the warning, but given the value it seems to be providing, that seems reasonable. I've filed the bug upstream: https://github.com/llvm/llvm-project/issues/94138 I also had to use some hacks to work around limitations of Bazel rules that wrap `cc_library` rules and don't expose `copts`. I filed a bug for `cc_proto_library` specifically: ~https://github.com/bazelbuild/bazel/issues/22610~ https://github.com/bazelbuild/bazel/issues/4446
