Thanks for the patch.
I think 'char' shouldn't be considered modulo even if
-funsigned-char -- I will bring this to LWG attention.
Why not? If an implementation decides to guarantee that the arithmetic on
a type is modular, it should advertise it through this trait, I don't see
anything wrong about that. Well, doing arithmetic on char may not be the
best idea, but still... Actually, if you are going to bring this up in
LWG, let's not discuss that here.
Note that I can't commit, you'll have to do it, sorry...
