So I guess we have a name collision here. Something to consider is that
GNU Make defines 'checks' as running self tests. So perhaps you are
correct to use that word.

I could rename the static analyses to 'analyze' or 'lint'. OTOH it might
be better if running the self tests is called 'make
run-{c,shell}-api-tests', because only a few people need to do
that. Whereas it is intended that all contributors run the static
analyses checks.

Although, if someone runs 'make check' in the lib directory, then it
makes sense to run the C API tests as well as do the analyses. Or not?

Thanks, I guess this shows that libclang is well supported.

Yeah, we do not want a mixture of check and checks. I should probably
just make it 'check' as it saves typing one letter.
