No, wrong question, it should be "what right does it have to be?" :) 6.6p7 states the semantics of constant expressions in initializers, of which this is one. It is none of the four because of the "a". This is only semantics, not a constraint, so an implementation can accept other stuff as extensions, but I don't believe you were writing extensions. By the flip side of the coin, your expression doesn't violate a constraint, but nor does it follow the semantics of the language, so a conforming implementation has no requirement to accept your expression. Many don't. Neil. _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
