[GitMensch]

consider to either include libjson-c or copying cJSON.[ch] into the libcob folder

concerning the one failed test:

I believe this has to do with the bundle/loadable module VS dynamic library thing specific to MacOS. I have no idea how to fix that either (and no will to delve into MacOS insanities - I have to preserve my own sanity).

Far sanity purpose: let's use AT_XFAIL_IF ($COB_MODULE_EXT="dylib") in this test (with some useful description in a comment up-front.

But that looks highly suspicions: sed -i '' 's/-undefined suppress//g' config.h what are we doing here and why?

Concerning the addition of libjson-c / cJSON-[hc]: without that we don't build and test a complete module (the JSON part).

Alright.

See comment above.

Yeah, I realized meanwhile and made the change ;)

[GitMensch]

All checks pass - YAY. As noted: please adjust the typo for "ototype" in configure.ac as well and check that in upstream together with a Changelog entry. As we do change something "quite big" for darwin, it is likely a good idea to also note that in NEWS, what do you think?

After doing the configure.ac related changes upstream, this PR needs to be rebased (or adjusted to only change the mirror-only workflow definitions).

Changes done. I also added a NEWS entry, because this is indeed an important change.

I'll do that in the morning.
