In both cases, because it is file scope, a and b need to be
initialized with constant expressions. I don´t see anything more
special in b compared with a to make any distinction. 

 
As of C23, you're right.  But what if a future C standard allows
non-constant initializers for file-scope object (as C++ already does)?
 

You mean, initializers by arbitrary user code running before main?
Hopefully, it would never happen. Too much against the virtue of C.
