I wasn't there, so I can't attest to accuracy. It does look like a
reasonable plan for gcc-14 though.

Not to open a can of worms, but shouldn't these be evaluated along the
same basic criteria? ie, what's Clang doing here, are these
warnings-as-errors and thus apply to system headers, etc. ANd the
biggie, do any of these issues tend to mask correctness errors in the
wild at a level roughly similar to implicit
int/implicit-function-declaration?
