The text is the same in both versions:
http://dev.unicals.com/papers/c89-draft.html#3.3.2.2
"The order of evaluation of the function designator, the arguments, and
subexpressions within the arguments is unspecified, but there is a
sequence point before the actual call."
(On reading this more closely, I suppose you could make the argument
that a function call that takes place in the argument list of another
function call is a "subexpression within the [outer function's]
arguments", so the order of evaluation prior to the call of the outer
function would be undefined. But I don't think that's the right reading
of the standard.)
