1508 (make_binding_level): Use ggc_alloc_cleared or memset.
1509 (lookup_tag): Remove struct binding_level* parameter. All
1510 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1511 current_binding_level->tags if asked for thislevel_only or if
1512 we might have to diagnose "struct foo; union foo;"
1513 (pushlevel): Ignore argument. Do not push another binding
1514 level on the transition from the parameters to the top level
1515 of the function body; just tweak the flags and proceed.

1517 a function body, separate the parameter list from the
1518 top-level local variables.
1519 (set_block): Do nothing.

1563 (c_print_identifier): Update to match changes to struct
1565 (poplevel): Delete #if 0 block. Make externals invisible
1566 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1567 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1568 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1569 (duplicate-decls): For real parm decl after a forward decl,
1570 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1571 foo(...) { } with only a warning. Say whether a previous
1572 declaration was implicit.
1573 (warn_if_shadowing): Now handles all shadowing, not just
1574 local-over-local. Clarify comments.
1575 (pushdecl): Rewritten. There is no longer a distinction
1576 between global and local symbol values; they're all
1577 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1578 DECL_EXTERNAL decls, and use any_external_decl to check
1579 against previous externals. Kill #if 0 blocks. Don't
1580 tolerate error_mark_node being NULL.

1582 Objective C (the only user) needs.
1583 (pushdecl_function_level): New function.
1584 (implicitly_declare): Create ordinary decls with
