It's yours, not mine.  Did you intend this remark to be about my
version?

If so, then it's not "excess verbosity".  The extra "(unsigned)" makes
the code work as you intended it to.  I'd call that required verbosity.
(It's not minimal since you can get the same effect in fewer
characters.)

If they are using such an implementation, they can do exactly as you
describe -- at the expense of portability.  UB means the implementation
may define the code as doing what the compiler's customers want.

Why are you asking me?

I don't know (did you think I might?).  In this particular case I see no
cost at all (at least on most architectures).

By the way, what are the scare quotes for?  They come over as sneering.
