Nando,
        that's not specialized.  The two catch clauses do the same thing (i.e.,
the same exception that's caught is rethrown.)  Did you have any
problems with the previous version? What behavior did you see that you
were trying to fix?

The first clause will try to rethrow a sliced down copy of e.
std::exception can't be constructed for a string. waht() method of the
rethrown object will return some implementation dependent message, not
the original error message.

Correct--see the attached test program.  You're slicing the message
away, so it seems like you're doing the opposite of what you meant...

Later,
