2379 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
2380 Improve some commentary. Adjust handling of forward parm decls.
2381 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
2382 Preserve C_DECL_IN_EXTERNAL_SCOPE.
2383 (warn_if_shadowing): Correct indentation. Improve diagnostics.

2448 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
2449 correct loop over multiple translation units; call fatal_error if
2450 requested to compile more than one file at once. (This disables
2451 IMA temporarily - an up-front error being preferable to a crash.)
2452 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
2453 (all actions): Adjust calls to pushlevel/poplevel.
