9702 we might have to diagnose "struct foo; union foo;"
9703 (pushlevel): Ignore argument. Do not push another binding
9704 level on the transition from the parameters to the top level
9705 of the function body; just tweak the flags and proceed.

9755 (poplevel): Delete #if 0 block. Make externals invisible
9756 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9757 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9758 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9759 (duplicate-decls): For real parm decl after a forward decl,
9760 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9761 foo(...) { } with only a warning. Say whether a previous
9762 declaration was implicit.

9764 local-over-local. Clarify comments.
9765 (pushdecl): Rewritten. There is no longer a distinction
9766 between global and local symbol values; they're all
9767 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9768 DECL_EXTERNAL decls, and use any_external_decl to check
9769 against previous externals. Kill #if 0 blocks. Don't
9770 tolerate error_mark_node being NULL.

9772 Objective C (the only user) needs.
9773 (pushdecl_function_level): New function.
9774 (implicitly_declare): Create ordinary decls with

9790 from build_external_ref.

9795 IDENTIFIER_GLOBAL_VALUE.
