9065 (make_binding_level): Use ggc_alloc_cleared or memset.
9066 (lookup_tag): Remove struct binding_level* parameter. All

9068 current_binding_level->tags if asked for thislevel_only or if
9069 we might have to diagnose "struct foo; union foo;"
9070 (pushlevel): Ignore argument. Do not push another binding
9071 level on the transition from the parameters to the top level
9072 of the function body; just tweak the flags and proceed.

9074 a function body, separate the parameter list from the
9075 top-level local variables.
9076 (set_block): Do nothing.

9122 (poplevel): Delete #if 0 block. Make externals invisible
9123 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9124 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9125 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9126 (duplicate-decls): For real parm decl after a forward decl,
9127 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

9131 local-over-local. Clarify comments.

9139 Objective C (the only user) needs.
9140 (pushdecl_function_level): New function.
