5574 we might have to diagnose "struct foo; union foo;"
5575 (pushlevel): Ignore argument. Do not push another binding
5576 level on the transition from the parameters to the top level
5577 of the function body; just tweak the flags and proceed.

5580 top-level local variables.

5625 (c_print_identifier): Update to match changes to struct
5627 (poplevel): Delete #if 0 block. Make externals invisible
5628 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5629 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5630 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5631 (duplicate-decls): For real parm decl after a forward decl,
5632 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
5633 foo(...) { } with only a warning. Say whether a previous
5634 declaration was implicit.
5635 (warn_if_shadowing): Now handles all shadowing, not just
5636 local-over-local. Clarify comments.
5637 (pushdecl): Rewritten. There is no longer a distinction
5638 between global and local symbol values; they're all
5639 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
5640 DECL_EXTERNAL decls, and use any_external_decl to check
5641 against previous externals. Kill #if 0 blocks. Don't
5642 tolerate error_mark_node being NULL.

5644 Objective C (the only user) needs.
5645 (pushdecl_function_level): New function.
5646 (implicitly_declare): Create ordinary decls with
5647 C_DECL_IMPLICIT set. Recycle old decls, however they got

5662 from build_external_ref.

5667 IDENTIFIER_GLOBAL_VALUE.
