2325 * c-common.h: Update prototypes.
2326 * c-decl.c (struct c_scope): Update commentary. Remove names,

2335 (poplevel): Rename to pop_scope; totally rewritten for new bindings
2337 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
2338 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
2339 Improve some commentary. Adjust handling of forward parm decls.
2340 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
2341 Preserve C_DECL_IN_EXTERNAL_SCOPE.
2342 (warn_if_shadowing): Correct indentation. Improve diagnostics.
2343 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
2344 decls. Rewrite for new bindings structures. Improve commentary.
2345 Eliminate the copy_node call.
2346 (implicit_decl_warning): Use the "diag" idiom (as seen in
2347 locate_old_decl) to reduce code duplication; call locate_old_decl
2348 if appropriate. Relocate to remove need for forward declaration.
2349 (implicitly_declare): Adjust for new bindings structures. Kludge
2350 around Objective-C not-really-builtin functions.

2362 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
2363 First scope pushed is the external scope, not the global scope.

2369 (grokparms): Return 0 if arg_types is error_mark_node.
2370 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
2371 reversed sense. Rewrite for new bindings structures. Do not
2372 leave any decls in the scope, to prevent pop_scope from doing
2373 contradictory things with them.
2374 (finish_struct, finish_enum): Remove redundant diagnostics.
2375 (build_enumerator): Don't cascade diagnostics for error_mark_node.
2376 Mark location where -pedantic changes the meaning of the program.

2407 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
2408 correct loop over multiple translation units; call fatal_error if
2409 requested to compile more than one file at once. (This disables
2410 IMA temporarily - an up-front error being preferable to a crash.)
2411 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
2412 (all actions): Adjust calls to pushlevel/poplevel.
2413 (parsing_iso_function_signature): Delete.
2414 (extdef_1): Fold into extdef.

2419 commented-out productions.

2422 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
2423 to suppress -Wold-style-definition after this error.
2424 (c_parse_file): Don't clear the binding stack or call
2425 finish_fname_decls here. Correct comment.
2426 * c-typeck.c (same_translation_unit_p): Export.
