1031 (make_binding_level): Use ggc_alloc_cleared or memset.
1032 (lookup_tag): Remove struct binding_level* parameter. All

1034 current_binding_level->tags if asked for thislevel_only or if
1035 we might have to diagnose "struct foo; union foo;"
1036 (pushlevel): Ignore argument. Do not push another binding
1037 level on the transition from the parameters to the top level
1038 of the function body; just tweak the flags and proceed.

1041 top-level local variables.

1086 (c_print_identifier): Update to match changes to struct
1088 (poplevel): Delete #if 0 block. Make externals invisible
1089 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1090 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1091 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1092 (duplicate-decls): For real parm decl after a forward decl,
1093 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1097 local-over-local. Clarify comments.

1105 Objective C (the only user) needs.
1106 (pushdecl_function_level): New function.
1107 (implicitly_declare): Create ordinary decls with
