5499 (make_binding_level): Use ggc_alloc_cleared or memset.
5500 (lookup_tag): Remove struct binding_level* parameter. All

5502 current_binding_level->tags if asked for thislevel_only or if
5503 we might have to diagnose "struct foo; union foo;"
5504 (pushlevel): Ignore argument. Do not push another binding
5505 level on the transition from the parameters to the top level
5506 of the function body; just tweak the flags and proceed.

5508 a function body, separate the parameter list from the
5509 top-level local variables.
5510 (set_block): Do nothing.

5556 (poplevel): Delete #if 0 block. Make externals invisible
5557 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5558 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5559 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5560 (duplicate-decls): For real parm decl after a forward decl,
5561 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

5565 local-over-local. Clarify comments.

5573 Objective C (the only user) needs.
5574 (pushdecl_function_level): New function.
