99 (objc_mark_locals_volatile): Update for new bindings structures.

105 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
106 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
107 Improve some commentary. Adjust handling of forward parm decls.
108 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
109 Preserve C_DECL_IN_EXTERNAL_SCOPE.
110 (warn_if_shadowing): Correct indentation. Improve diagnostics.

138 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with

141 contradictory things with them.
142 (finish_struct, finish_enum): Remove redundant diagnostics.
143 (build_enumerator): Don't cascade diagnostics for error_mark_node.
144 Mark location where -pedantic changes the meaning of the program.

178 IMA temporarily - an up-front error being preferable to a crash.)
179 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
180 (all actions): Adjust calls to pushlevel/poplevel.
181 (parsing_iso_function_signature): Delete.
