9032 (make_binding_level): Use ggc_alloc_cleared or memset.
9033 (lookup_tag): Remove struct binding_level* parameter. All

9035 current_binding_level->tags if asked for thislevel_only or if
9036 we might have to diagnose "struct foo; union foo;"
9037 (pushlevel): Ignore argument. Do not push another binding
9038 level on the transition from the parameters to the top level
9039 of the function body; just tweak the flags and proceed.

9041 a function body, separate the parameter list from the
9042 top-level local variables.
9043 (set_block): Do nothing.

9055 empty functions. Otherwise, don't call poplevel.

9087 (c_print_identifier): Update to match changes to struct
9089 (poplevel): Delete #if 0 block. Make externals invisible
9090 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9091 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9092 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9093 (duplicate-decls): For real parm decl after a forward decl,
9094 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9095 foo(...) { } with only a warning. Say whether a previous
9096 declaration was implicit.
9097 (warn_if_shadowing): Now handles all shadowing, not just
9098 local-over-local. Clarify comments.
9099 (pushdecl): Rewritten. There is no longer a distinction
9100 between global and local symbol values; they're all
9101 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9102 DECL_EXTERNAL decls, and use any_external_decl to check
9103 against previous externals. Kill #if 0 blocks. Don't
9104 tolerate error_mark_node being NULL.

9106 Objective C (the only user) needs.
9107 (pushdecl_function_level): New function.
9108 (implicitly_declare): Create ordinary decls with
