The problems with C are real.

At the same time, the tooling has gotten much better in the last years.

Clang-analyzer is fast enough to run as part of the CI. Newer gcc also give quite a few more warnings for unused results.

My recommendation to the project is to

- Remove all compiler warnings and enable warning-as-error

- Increase the coverage of unit tests to >80%

That is a lot of work. But that's what is required for high-criticality systems engineering.
