9625 current_binding_level->tags if asked for thislevel_only or if
9626 we might have to diagnose "struct foo; union foo;"
9627 (pushlevel): Ignore argument. Do not push another binding
9628 level on the transition from the parameters to the top level
9629 of the function body; just tweak the flags and proceed.

9631 a function body, separate the parameter list from the
9632 top-level local variables.
9633 (set_block): Do nothing.

9645 empty functions. Otherwise, don't call poplevel.

9677 (c_print_identifier): Update to match changes to struct
9679 (poplevel): Delete #if 0 block. Make externals invisible
9680 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9681 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9682 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9683 (duplicate-decls): For real parm decl after a forward decl,
9684 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9685 foo(...) { } with only a warning. Say whether a previous
9686 declaration was implicit.
9687 (warn_if_shadowing): Now handles all shadowing, not just
9688 local-over-local. Clarify comments.
9689 (pushdecl): Rewritten. There is no longer a distinction
9690 between global and local symbol values; they're all
9691 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9692 DECL_EXTERNAL decls, and use any_external_decl to check
9693 against previous externals. Kill #if 0 blocks. Don't
9694 tolerate error_mark_node being NULL.
9695 (pushdecl_top_level): Handle only those cases which
9696 Objective C (the only user) needs.
9697 (pushdecl_function_level): New function.
9698 (implicitly_declare): Create ordinary decls with
9699 C_DECL_IMPLICIT set. Recycle old decls, however they got

9714 from build_external_ref.

9719 IDENTIFIER_GLOBAL_VALUE.
