No. You are trying to identify the absence of something i.e. the lack of
default constructor. Declare warning/error can only be used to advise join
points that exist. They cannot be used where the joint point does not
exist.

From previous postings it seems that your application has the requirement
for the existence of default constructors. May I ask what the root
requirement is?
