9380 (poplevel): Rename to pop_scope; totally rewritten for new bindings
9382 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
9383 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
9384 Improve some commentary. Adjust handling of forward parm decls.
9385 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
9386 Preserve C_DECL_IN_EXTERNAL_SCOPE.
9387 (warn_if_shadowing): Correct indentation. Improve diagnostics.

9408 First scope pushed is the external scope, not the global scope.

9452 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
9453 correct loop over multiple translation units; call fatal_error if
9454 requested to compile more than one file at once. (This disables
9455 IMA temporarily - an up-front error being preferable to a crash.)
