	Fri Oct 23 18:52:19 1992  Brendan Kehoe  ([e-mail])

	* cp-decl.c (poplevel): Use error_with_decl on an unused label, so

	* cp-decl.c (pushdecl): Since the rest of the compiler wants to use
	DECL_NAME for TYPE_DECLs, use that instead of DECL_ASSEMBLER_NAME.

	how it walks the inheritance hierarchy so that when we get down to
	the bottom, we have a pointer to what we want.

	pointer instead of incorrectly trying to convert at the bottom.
	* cp-search.c (init_vbase_pointers): Changed to set up new
