We know that, but I don't think most C/C++ programmers know about integer
promotion rules. We just disagree here. But since this is mandated by the
standard, you are right.

For a strict-standard definition of "fits", because it may overflow and a
layman wouldn't say that it "fits" in that case.

I am not arguing against that (although, I think it is unfortunate). I would
prefer a bit longer message:
error: C++0x does not allow narrowing conversion of "(((int)y) + 1)" from "int"
to "char" inside { }
(BTW, I think those braces should be within quotes).
But since I guess I am in the minority here, we'll have to close this as
INVALID.
