1053 (make_binding_level): Use ggc_alloc_cleared or memset.
1054 (lookup_tag): Remove struct binding_level* parameter. All

1056 current_binding_level->tags if asked for thislevel_only or if
1057 we might have to diagnose "struct foo; union foo;"
1058 (pushlevel): Ignore argument. Do not push another binding
1059 level on the transition from the parameters to the top level
1060 of the function body; just tweak the flags and proceed.

1063 top-level local variables.

1110 (poplevel): Delete #if 0 block. Make externals invisible
1111 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1112 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1113 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1114 (duplicate-decls): For real parm decl after a forward decl,
1115 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1119 local-over-local. Clarify comments.

1127 Objective C (the only user) needs.
