1453 (make_binding_level): Use ggc_alloc_cleared or memset.
1454 (lookup_tag): Remove struct binding_level* parameter. All
1455 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1456 current_binding_level->tags if asked for thislevel_only or if
1457 we might have to diagnose "struct foo; union foo;"
1458 (pushlevel): Ignore argument. Do not push another binding
1459 level on the transition from the parameters to the top level
1460 of the function body; just tweak the flags and proceed.
1461 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1462 a function body, separate the parameter list from the
1463 top-level local variables.
1464 (set_block): Do nothing.

1466 shadowed_tags if necessary.

1476 empty functions. Otherwise, don't call poplevel.
1478 * c-common.c (shadow_warning): MANDATORY argument is no longer
1479 necessary. Always use plain warning.
1480 * c-common.h: Update to match.

1508 (c_print_identifier): Update to match changes to struct
1510 (poplevel): Delete #if 0 block. Make externals invisible
1511 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1512 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1513 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1514 (duplicate-decls): For real parm decl after a forward decl,
1515 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1516 foo(...) { } with only a warning. Say whether a previous
1517 declaration was implicit.
1518 (warn_if_shadowing): Now handles all shadowing, not just
1519 local-over-local. Clarify comments.
1520 (pushdecl): Rewritten. There is no longer a distinction
1521 between global and local symbol values; they're all
1522 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1523 DECL_EXTERNAL decls, and use any_external_decl to check
1524 against previous externals. Kill #if 0 blocks. Don't
1525 tolerate error_mark_node being NULL.

1527 Objective C (the only user) needs.
1528 (pushdecl_function_level): New function.
1529 (implicitly_declare): Create ordinary decls with

1545 from build_external_ref.

1550 IDENTIFIER_GLOBAL_VALUE.
