1528 (make_binding_level): Use ggc_alloc_cleared or memset.
1529 (lookup_tag): Remove struct binding_level* parameter. All

1531 current_binding_level->tags if asked for thislevel_only or if
1532 we might have to diagnose "struct foo; union foo;"
1533 (pushlevel): Ignore argument. Do not push another binding
1534 level on the transition from the parameters to the top level
1535 of the function body; just tweak the flags and proceed.

1537 a function body, separate the parameter list from the
1538 top-level local variables.
1539 (set_block): Do nothing.

1585 (poplevel): Delete #if 0 block. Make externals invisible
1586 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1587 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1588 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1589 (duplicate-decls): For real parm decl after a forward decl,
1590 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1594 local-over-local. Clarify comments.

1602 Objective C (the only user) needs.
