At first glance it looked fine, at second glance the use of conditions is suspiciously inconsistent – they contradict each other. Please examine it.

Reversing the condition is obviously wrong.

There are still broken conditions for which it is necessary to revert it to the original sense.

Well, now I'm happy with the result – finally – I know I have high demands. However – one more requirement. There's no point in having so many commits. Please squash it into a single commit.

All ready. Thanks for the patience. :-)

It looks good, I have no further objections.

@selk: That looks much better than before. Keep up your efforts. 👍

It's good you look at this LibreSSL, musl and other things and test them.
