X-Git-Tag: prereleases/libstdc++-2.92~2891

decl.c (init_decl_processing): Correct name of pure virtual function under the new ABI.

	* decl.c (init_decl_processing): Correct name of pure virtual
	function under the new ABI.
	* rtti.c (throw_bad_cast): Likewise, for bad cast function.
	(throw_bad_typeid): Likewise for bad typeid function.

	* libsupc++/exception_support.cc (__throw_bad_cast): Name it
	__cxa_bad_cast under the new ABI.
	(__throw_bad_typeid): Name it __cxa_bad_typeid under the new ABI.
	* libsupc++/pure.cc (__pure_virtual): Name it __cxa_pure_virtual
	under the new ABI.
