I'm still secretly hoping that one fine day one of your minions will
come with a conversion series around the corner; series, which gets rid
of this unreadable mess and we get something *actually* readable like

And on that day I'll even take one patch per severities[] member so that
it is absolutely clear how the conversion has happened and review can be
good and catch any lurking errors.

One day... :-)

Because after that day, we can do arbitrary rules to adjust the severity
and there won't be any problems with extending it anymore because then
it'll be nice and flexible C code only.

Ok, feel free to adjust it how you think it is better.

Nah, I just put it there so that I can see the macros in the same window
and don't have to scroll - I'm purely relying on you here to place it in
the right spot.
