6423 (make_binding_level): Use ggc_alloc_cleared or memset.
6424 (lookup_tag): Remove struct binding_level* parameter. All

6426 current_binding_level->tags if asked for thislevel_only or if
6427 we might have to diagnose "struct foo; union foo;"
6428 (pushlevel): Ignore argument. Do not push another binding
6429 level on the transition from the parameters to the top level
6430 of the function body; just tweak the flags and proceed.

6433 top-level local variables.
6434 (set_block): Do nothing.

6480 (poplevel): Delete #if 0 block. Make externals invisible
6481 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6482 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6483 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6484 (duplicate-decls): For real parm decl after a forward decl,
6485 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

6489 local-over-local. Clarify comments.

6497 Objective C (the only user) needs.
6498 (pushdecl_function_level): New function.
