The way that I interpret this is that an array of character type may be initialized by a character string literal, and a parenthesized string literal has the same semantics as a string literal so it may be used as well (this text is under the semantics section). Also, I don't see how the warning is correct with the interpretation that it has to be specifically an expression that is a string literal and nothing more complicated given that _Generic is accepted.
