10725 we might have to diagnose "struct foo; union foo;"
10726 (pushlevel): Ignore argument. Do not push another binding
10727 level on the transition from the parameters to the top level
10728 of the function body; just tweak the flags and proceed.

10775 (clone_underlying type): Split out of pushdecl.
10776 (c_print_identifier): Update to match changes to struct
10778 (poplevel): Delete #if 0 block. Make externals invisible
10779 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10780 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10781 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10782 (duplicate-decls): For real parm decl after a forward decl,
10783 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10784 foo(...) { } with only a warning. Say whether a previous

10787 local-over-local. Clarify comments.
10788 (pushdecl): Rewritten. There is no longer a distinction
10789 between global and local symbol values; they're all
10790 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10791 DECL_EXTERNAL decls, and use any_external_decl to check
10792 against previous externals. Kill #if 0 blocks. Don't
10793 tolerate error_mark_node being NULL.
10794 (pushdecl_top_level): Handle only those cases which
10795 Objective C (the only user) needs.
10796 (pushdecl_function_level): New function.
10797 (implicitly_declare): Create ordinary decls with
10798 C_DECL_IMPLICIT set. Recycle old decls, however they got
