1902 (objc_mark_locals_volatile): Update for new bindings structures.
1903 (global_bindings_p): Honor c_override_global_bindings_to_false.
1904 (pushlevel): Rename to push_scope; take no arguments; use the
1905 scope_freelist; initialize scope->depth and check for overflow.
1906 (poplevel): Rename to pop_scope; totally rewritten for new bindings
1908 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
1909 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
1910 Improve some commentary. Adjust handling of forward parm decls.
1911 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
1912 Preserve C_DECL_IN_EXTERNAL_SCOPE.
1913 (warn_if_shadowing): Correct indentation. Improve diagnostics.

1915 decls. Rewrite for new bindings structures. Improve commentary.
1916 Eliminate the copy_node call.
1917 (implicit_decl_warning): Use the "diag" idiom (as seen in
1918 locate_old_decl) to reduce code duplication; call locate_old_decl

1933 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
1934 First scope pushed is the external scope, not the global scope.

1941 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
1942 reversed sense. Rewrite for new bindings structures. Do not

1978 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
1979 correct loop over multiple translation units; call fatal_error if
1980 requested to compile more than one file at once. (This disables
1981 IMA temporarily - an up-front error being preferable to a crash.)
1982 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
1983 (all actions): Adjust calls to pushlevel/poplevel.
1984 (parsing_iso_function_signature): Delete.

1994 to suppress -Wold-style-definition after this error.
