Warning when compiling with -Wdeprecated-dynamic-exception-spec in clang

[viboes]

When compiling with -Wdeprecated-dynamic-exception-spec in clang we get the following warning

/xxx/modular-boost3/boost/smart_ptr/bad_weak_ptr.hpp:50:39: error: dynamic exception specifications are deprecated [-Werror,-Wdeprecated-dynamic-exception-spec]
    virtual char const * what() const throw()
                                      ^~~~~~~
/Users/viboes/github/modular-boost3/boost/smart_ptr/bad_weak_ptr.hpp:50:39: note: use 'noexcept' instead

                                      noexcept

I don't know if using instead BOOST_NOEXCEPT_OR_NOTHROW is correct and should resolve the issue.
