3125 (make_binding_level): Use ggc_alloc_cleared or memset.
3126 (lookup_tag): Remove struct binding_level* parameter. All

3128 current_binding_level->tags if asked for thislevel_only or if
3129 we might have to diagnose "struct foo; union foo;"
3130 (pushlevel): Ignore argument. Do not push another binding
3131 level on the transition from the parameters to the top level
3132 of the function body; just tweak the flags and proceed.

3134 a function body, separate the parameter list from the
3135 top-level local variables.
3136 (set_block): Do nothing.

3138 shadowed_tags if necessary.

3148 empty functions. Otherwise, don't call poplevel.

3180 (c_print_identifier): Update to match changes to struct
3182 (poplevel): Delete #if 0 block. Make externals invisible
3183 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
3184 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
3185 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
3186 (duplicate-decls): For real parm decl after a forward decl,
3187 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
3188 foo(...) { } with only a warning. Say whether a previous
3189 declaration was implicit.
3190 (warn_if_shadowing): Now handles all shadowing, not just
3191 local-over-local. Clarify comments.
3192 (pushdecl): Rewritten. There is no longer a distinction
3193 between global and local symbol values; they're all
3194 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
3195 DECL_EXTERNAL decls, and use any_external_decl to check
3196 against previous externals. Kill #if 0 blocks. Don't
3197 tolerate error_mark_node being NULL.
3198 (pushdecl_top_level): Handle only those cases which
3199 Objective C (the only user) needs.
