Grrr... so stupid! :-)
Yes, you are right. I stumbled that only a few lines generates an error. Yes,
the compiler optimize them out if the access is direct. With -O3
it compiles and links without errors also without having const int A::x

Yes. You need to define A::x.
Add this line:
const int A::x;
If the code is wrong, I expect a compiler error not a linker message!
No, because A::x might be defined in another translation unit.
