9588 we might have to diagnose "struct foo; union foo;"
9589 (pushlevel): Ignore argument. Do not push another binding
9590 level on the transition from the parameters to the top level
9591 of the function body; just tweak the flags and proceed.

9641 (poplevel): Delete #if 0 block. Make externals invisible
9642 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9643 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9644 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9645 (duplicate-decls): For real parm decl after a forward decl,
9646 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

9650 local-over-local. Clarify comments.

9658 Objective C (the only user) needs.
9659 (pushdecl_function_level): New function.
9660 (implicitly_declare): Create ordinary decls with
