The evaluation order of parameters is > unspecified in C, so actually the order could be switched or not, > depending on what the compiler chooses to do. But you could rewrite the code so that the parameters are evaluated one after the other, and only after that call Fcons. The compiler could still change the order, but that would be less probable. > That being said, AFAICS it doesn't matter in this case, indeed. It is IME better to write code that doesn't trigger such questions to begin with. > Eli, OK to install? With the change of order per the above, yes. Thanks.
