Well, like it or it, it will stay.

It is needed if:

	* You want to link C & C++ together.

	* You use exceptions.

	* you use block profiling.

	* You write code which uses the constructor or destructor
	attributes.

	* Shared libraries need to be self-contained in respect
	to compiler intrinsics -- which include the EH mechanisms.

	ie, the library must have its own copy of those routines.

	Yes, this means we have to keep old interfaces for compiler
	intrinsics around.  But that's just the price we have to
	pay.
