2363 (poplevel): Rename to pop_scope; totally rewritten for new bindings
2365 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
2366 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
2367 Improve some commentary. Adjust handling of forward parm decls.
2368 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
2369 Preserve C_DECL_IN_EXTERNAL_SCOPE.
2370 (warn_if_shadowing): Correct indentation. Improve diagnostics.

2373 Eliminate the copy_node call.

2390 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
2391 First scope pushed is the external scope, not the global scope.

2398 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
2399 reversed sense. Rewrite for new bindings structures. Do not

2435 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
2436 correct loop over multiple translation units; call fatal_error if
2437 requested to compile more than one file at once. (This disables
2438 IMA temporarily - an up-front error being preferable to a crash.)
2439 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
2440 (all actions): Adjust calls to pushlevel/poplevel.
2441 (parsing_iso_function_signature): Delete.

2451 to suppress -Wold-style-definition after this error.
