3239 (grokparms): Return 0 if arg_types is error_mark_node.
3240 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with

3244 (finish_struct, finish_enum): Remove redundant diagnostics.
3245 (build_enumerator): Don't cascade diagnostics for error_mark_node.
3246 Mark location where -pedantic changes the meaning of the program.
