2371 (poplevel): Rename to pop_scope; totally rewritten for new bindings
2373 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
2374 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
2375 Improve some commentary. Adjust handling of forward parm decls.
2376 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
2377 Preserve C_DECL_IN_EXTERNAL_SCOPE.
2378 (warn_if_shadowing): Correct indentation. Improve diagnostics.

2399 First scope pushed is the external scope, not the global scope.

2443 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
2444 correct loop over multiple translation units; call fatal_error if
2445 requested to compile more than one file at once. (This disables
2446 IMA temporarily - an up-front error being preferable to a crash.)
2447 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
2448 (all actions): Adjust calls to pushlevel/poplevel.
