If you look closely, you'll see that this code was added to
pp_cxx_unary_expression (and even mentioned in the ChangeLog)
precisely because of the helpful comment you cited. The thing
that might have been confusing is that because the syntax is:
>> /* unary-expression:
>> ...
>> unary-operator cast-expression
we now need to call "cast-expression" from "unary-expression".
As a result, with my change pp_cxx_unary_expression needs to invoke
pp_cxx_cast_expression, which unfortunately is defined later in the
source file. As a result, I have to add a new prototype for the
function pp_cxx_cast_expression even though my functional change
is to pp_cxx_unary_expression.
I hope this make sense.
Thanks for the review.
Roger
