6606 (pushlevel): Ignore argument. Do not push another binding
6607 level on the transition from the parameters to the top level
6608 of the function body; just tweak the flags and proceed.

6658 (poplevel): Delete #if 0 block. Make externals invisible
6659 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6660 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6661 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6662 (duplicate-decls): For real parm decl after a forward decl,
6663 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

6667 local-over-local. Clarify comments.

6675 Objective C (the only user) needs.
