	STDCXX-262
	* exception (~exception): Declared after what() to prevent gcc 4
	on Darwin from generating a vtable for the class in exception.o.
	gcc 3.4.6 on FreeBSD 6.2 has no problem either way.
	(~bad_exception): Declared before what() to achieve the same
	effect as above.
	* new (~bad_alloc): Declared before what() for the same reason.
