Well, it's not that it's "wrong," but that it could be so much better.
Exceptions can be objects in their own right.  That would permit one to have
sets, prioritized lists, whatever of exceptions. 

Your solution provides very inflexible exception handling.  You are trying to
make an exception handler look like a procedure.  But in C, that makes it even
more restrictive than the arrangement used in Ada: Not only are you
restricting how exceptions can be organized, but you are also allowing for
only one possible way to handle each exception!
