Thanks for doing this! Consistency with `tools/` is nice to have indeed.

I see that `compiler-gcc.h` is included for Clang too in `tools/`, so
it looks fine to me:

In the future, it could be nice to enable the warning for Clang too,
though I see it requires a few cleanups.

Another idea is to use something similar to `compiler_attributes.h` in
`tools/` (perhaps just copying it and removing what is not needed?).

Cheers,
