1866 scope_freelist; initialize scope->depth and check for overflow.
1867 (poplevel): Rename to pop_scope; totally rewritten for new bindings
1869 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
1870 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
1871 Improve some commentary. Adjust handling of forward parm decls.
1872 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
1873 Preserve C_DECL_IN_EXTERNAL_SCOPE.
1874 (warn_if_shadowing): Correct indentation. Improve diagnostics.
1875 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
1876 decls. Rewrite for new bindings structures. Improve commentary.
1877 Eliminate the copy_node call.
1878 (implicit_decl_warning): Use the "diag" idiom (as seen in
1879 locate_old_decl) to reduce code duplication; call locate_old_decl
1880 if appropriate. Relocate to remove need for forward declaration.

1882 around Objective-C not-really-builtin functions.

1901 (grokparms): Return 0 if arg_types is error_mark_node.
1902 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
1903 reversed sense. Rewrite for new bindings structures. Do not
1904 leave any decls in the scope, to prevent pop_scope from doing
1905 contradictory things with them.
1906 (finish_struct, finish_enum): Remove redundant diagnostics.
1907 (build_enumerator): Don't cascade diagnostics for error_mark_node.
1908 Mark location where -pedantic changes the meaning of the program.

1939 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
1940 correct loop over multiple translation units; call fatal_error if
1941 requested to compile more than one file at once. (This disables
1942 IMA temporarily - an up-front error being preferable to a crash.)
1943 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
1944 (all actions): Adjust calls to pushlevel/poplevel.
1945 (parsing_iso_function_signature): Delete.

1955 to suppress -Wold-style-definition after this error.
1956 (c_parse_file): Don't clear the binding stack or call
1957 finish_fname_decls here. Correct comment.
1958 * c-typeck.c (same_translation_unit_p): Export.
