1521 (make_binding_level): Use ggc_alloc_cleared or memset.
1522 (lookup_tag): Remove struct binding_level* parameter. All

1524 current_binding_level->tags if asked for thislevel_only or if
1525 we might have to diagnose "struct foo; union foo;"
1526 (pushlevel): Ignore argument. Do not push another binding
1527 level on the transition from the parameters to the top level
1528 of the function body; just tweak the flags and proceed.

1531 top-level local variables.

1578 (poplevel): Delete #if 0 block. Make externals invisible
1579 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1580 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1581 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1582 (duplicate-decls): For real parm decl after a forward decl,
1583 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1587 local-over-local. Clarify comments.

1595 Objective C (the only user) needs.
