	gcc/cp         : ChangeLog cp-tree.def decl.c decl2.c rtti.c 
	                 typeck.c 

Log message:
	Handle anonymous unions at the tree level.
	C++ ABI change: Mangle anonymous unions using the name of their
	first named field (by depth-first search).  Should not cause
	binary compatibility problems, though, as the compiler previously
	didn't emit anything for affected unions.
	* cp-tree.def (ALIAS_DECL): New tree code.
	* decl2.c (build_anon_union_vars): Build ALIAS_DECLs.  Return the
	first field, not the largest.
	(finish_anon_union): Don't mess with RTL.  Do set DECL_ASSEMBLER_NAME,
	push the decl, and write it out at namespace scope.
	* decl.c (lookup_name_real): See through an ALIAS_DECL.
	(pushdecl): Add namespace bindings for ALIAS_DECLs.
	* rtti.c (unemitted_tinfo_decl_p): Don't try to look at the name
	of a decl which doesn't have one.
	* typeck.c (build_class_member_access_expr): Don't recurse if
	we already have the type we want.
