compiler errors

Attempting to link libc++ against libsupc++ produces a number of errors about
redefinition of std::bad_typeid::~bad_typeid() and std::bad_cast::~bad_cast()
(see attachment).

It appears that std::bad_cast and std::bad_typeid are provided by libsupc++.

libc++ should either avoid redefining them, or avoid pulling in the definitions
from libsupc++.

(I am using the version of libsupc++ from gcc 4.1.2 which ships with CentOS
5.9; however, I have no reason to believe this problem is limited to that
