1487 (make_binding_level): Use ggc_alloc_cleared or memset.
1488 (lookup_tag): Remove struct binding_level* parameter. All
1489 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1490 current_binding_level->tags if asked for thislevel_only or if
1491 we might have to diagnose "struct foo; union foo;"
1492 (pushlevel): Ignore argument. Do not push another binding
1493 level on the transition from the parameters to the top level
1494 of the function body; just tweak the flags and proceed.

1496 a function body, separate the parameter list from the
1497 top-level local variables.
1498 (set_block): Do nothing.

1542 (c_print_identifier): Update to match changes to struct
1544 (poplevel): Delete #if 0 block. Make externals invisible
1545 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1546 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1547 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1548 (duplicate-decls): For real parm decl after a forward decl,
1549 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1550 foo(...) { } with only a warning. Say whether a previous
1551 declaration was implicit.
1552 (warn_if_shadowing): Now handles all shadowing, not just
1553 local-over-local. Clarify comments.
1554 (pushdecl): Rewritten. There is no longer a distinction
1555 between global and local symbol values; they're all
1556 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1557 DECL_EXTERNAL decls, and use any_external_decl to check
1558 against previous externals. Kill #if 0 blocks. Don't
1559 tolerate error_mark_node being NULL.

1561 Objective C (the only user) needs.
1562 (pushdecl_function_level): New function.
1563 (implicitly_declare): Create ordinary decls with
