1474 (make_binding_level): Use ggc_alloc_cleared or memset.
1475 (lookup_tag): Remove struct binding_level* parameter. All

1477 current_binding_level->tags if asked for thislevel_only or if
1478 we might have to diagnose "struct foo; union foo;"
1479 (pushlevel): Ignore argument. Do not push another binding
1480 level on the transition from the parameters to the top level
1481 of the function body; just tweak the flags and proceed.

1531 (poplevel): Delete #if 0 block. Make externals invisible
1532 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1533 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1534 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1535 (duplicate-decls): For real parm decl after a forward decl,
1536 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1540 local-over-local. Clarify comments.
