4991 (poplevel): Rename to pop_scope; totally rewritten for new bindings
4993 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
4994 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
4995 Improve some commentary. Adjust handling of forward parm decls.
4996 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
4997 Preserve C_DECL_IN_EXTERNAL_SCOPE.
4998 (warn_if_shadowing): Correct indentation. Improve diagnostics.

5001 Eliminate the copy_node call.

5018 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
5019 First scope pushed is the external scope, not the global scope.

5063 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
5064 correct loop over multiple translation units; call fatal_error if
5065 requested to compile more than one file at once. (This disables
5066 IMA temporarily - an up-front error being preferable to a crash.)
