[Bug c++/29466] pointless error on implicit destructor

[pinskia at gcc dot gnu dot org]

Comeau also errors and I don't have access to the standard right at this moment
to double check.

"ComeauTest.c", line 3: error: exception specification for implicitly declared
          virtual function "der1::~der1" is incompatible with that of
          overridden function "std::exception::~exception"
  class der1 : public std::exception { std::string s;};
        ^

To reply to this part, you are incorrect in saying they are unknown and
changing throw specifications as the C++ standard defines them.
