Is your cc a gcc or clang? My one is clang and I didn't get build
errors when I tested the commit. I was told there are those errors with
gcc. My question in the corresponding thread is so far unanswered.
Here's what I wrote as a reference:

Does someone know what this is supposed to result in?
I would assume as the unions are unnamed and no variable is declared
inside the struct with it, that the size of the struct is the same as
not having those unions inside the structs.
If this is correct I would assume the correct fix would be to #if-0
them out.

Did you name it x ("union x {...};"), or did you declare a variable
x with it ("union {...} x;")?
Bye,
