re PR libstdc++/51438 (std::exception and derived classes are not compatible with std::nested_exception and C++11 in general)

2011-12-06  Paolo Carlini  <paolo.carlini@oracle.com>

	PR libstdc++/51438
	* libsupc++/nested_exception.h (nested_exception::~nested_exception):
	Declare noexcept.

	Likewise.

	* src/shared_ptr.cc: Use noexcept where appropriate.
	* include/std/system_error: Likewise.
	* include/std/functional: Likewise.
	* include/bits/shared_ptr_base.h: Likewise.
	* src/stdexcept.cc: Use _GLIBCXX_USE_NOEXCEPT where appropriate.
	* include/std/stdexcept: Likewise.
	* libsupc++/bad_cast.cc: Likewise.
	* libsupc++/bad_typeid.cc: Likewise.
	* libsupc++/eh_exception.cc: Likewise.
	* libsupc++/typeinfo: Likewise.
	* libsupc++/exception: Likewise.
	* libsupc++/eh_ptr.cc: Likewise.
