        * cp-tree.h (start_decl):  Update prototype.
        * decl.c (start_decl):  Like the C version, new parameters
        for the attributes.  Call cplus_decl_attributes here,
        (pushdecl):  Like C version, do build_type_copy if TYPE_DECL,
        (grokdeclarator):  Pass NULL for new start_decl arguments.
        * pt.c (tsubst_expr):  Likewise.
        * parse.y:  Merge cplus_decl_attribute calls into start_decl calls.
	* typeck.c (common_type): Check TYPE_MAIN_VARIANT.
	* lex.c (build_lang_decl): Add lang_name_java.
	* class.c (push_lang_context): Add lang_name_java.
	* method.c (build_mangled_name): Check for is_java_type.

	* decl.c (grokdeclarator): Check TYPE_MAIN_VARIANT.
	* call.c (build_scoped_method_call): Check for TREE_CODE for
	VOID_TYPE instead of type ==  void_type_node.
	(build_method_call): Ditto.
	* decl.c (lookup_name_real): Ditto.
	(grokdeclarator): Ditto.
	(start_decl): Ditto.
	(grokparms): Ditto.
	(start_function): Ditto.
	(finish_function): Ditto.
