11459 from the parms chain, nor to store them back afterward. Move
11460 declaration to top of function, restructure code reordering
11462 (store_parm_decls): No need to save and restore warn_shadow.
11463 * c-parse.in: Don't call parmlist_tags_warning nor
11464 clear_parm_order. Call mark_forward_parm_decls when forward
11465 parm decls are encountered.
