 Compiling  libs/optional/test/optional_test_swap.cpp with Oracle Solaris
 Studio 12.5 in C++11 mode, we see the following error:

 In C++03, the std::swap template does not have an exception
 specification. In C++11, it has a noexcept specification.


 This seems to be a violation of the standard.
 15.4[except.spec]p5:
 =====
 If any declaration of a function has an exception-specification that is
 not a
 noexcept-specification allowing
 all exceptions, all declarations, including the definition and any
 explicit
 specialization, of that function shall
 have a compatible exception-specification.
