Currently we never run tests in CI with-We.

» ag '\-W(e| error)' .github.github/workflows/build.yml79:        run: autoreconf -ivf -Werror

This might be a problem for several reasons:

• Warnings might be raised and unseen for quite some time
• -We can break something that it should not break, we never check for it

This is especially true forHypothesis runs, which has its own warnings, sometimes not very expected ones, like in#136384

My proposal: let's try to research if it is possible and if it is a good idea. And maybe eventually runHypothesis tests with-We in our CI.

Please, share your ideas / concerns about this change.
