1479 (make_binding_level): Use ggc_alloc_cleared or memset.
1480 (lookup_tag): Remove struct binding_level* parameter. All

1482 current_binding_level->tags if asked for thislevel_only or if
1483 we might have to diagnose "struct foo; union foo;"
1484 (pushlevel): Ignore argument. Do not push another binding
1485 level on the transition from the parameters to the top level
1486 of the function body; just tweak the flags and proceed.

1489 top-level local variables.

1534 (c_print_identifier): Update to match changes to struct
1536 (poplevel): Delete #if 0 block. Make externals invisible
1537 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1538 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1539 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1540 (duplicate-decls): For real parm decl after a forward decl,
1541 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1542 foo(...) { } with only a warning. Say whether a previous
1543 declaration was implicit.
1544 (warn_if_shadowing): Now handles all shadowing, not just
1545 local-over-local. Clarify comments.
1546 (pushdecl): Rewritten. There is no longer a distinction
1547 between global and local symbol values; they're all
1548 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1549 DECL_EXTERNAL decls, and use any_external_decl to check
1550 against previous externals. Kill #if 0 blocks. Don't

1553 Objective C (the only user) needs.
1554 (pushdecl_function_level): New function.
1555 (implicitly_declare): Create ordinary decls with
