8704 we might have to diagnose "struct foo; union foo;"
8705 (pushlevel): Ignore argument. Do not push another binding
8706 level on the transition from the parameters to the top level
8707 of the function body; just tweak the flags and proceed.

8757 (poplevel): Delete #if 0 block. Make externals invisible
8758 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
8759 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
8760 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8761 (duplicate-decls): For real parm decl after a forward decl,
8762 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
8763 foo(...) { } with only a warning. Say whether a previous
8764 declaration was implicit.

8766 local-over-local. Clarify comments.
8767 (pushdecl): Rewritten. There is no longer a distinction
8768 between global and local symbol values; they're all
8769 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
8770 DECL_EXTERNAL decls, and use any_external_decl to check
8771 against previous externals. Kill #if 0 blocks. Don't
8772 tolerate error_mark_node being NULL.

8774 Objective C (the only user) needs.
8775 (pushdecl_function_level): New function.
8776 (implicitly_declare): Create ordinary decls with
