1059 (make_binding_level): Use ggc_alloc_cleared or memset.
1060 (lookup_tag): Remove struct binding_level* parameter. All

1062 current_binding_level->tags if asked for thislevel_only or if
1063 we might have to diagnose "struct foo; union foo;"
1064 (pushlevel): Ignore argument. Do not push another binding
1065 level on the transition from the parameters to the top level
1066 of the function body; just tweak the flags and proceed.

1069 top-level local variables.
1070 (set_block): Do nothing.

1116 (poplevel): Delete #if 0 block. Make externals invisible
1117 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1118 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1119 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1120 (duplicate-decls): For real parm decl after a forward decl,
1121 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1125 local-over-local. Clarify comments.

1133 Objective C (the only user) needs.
1134 (pushdecl_function_level): New function.
