4796 (pushlevel): Ignore argument. Do not push another binding
4797 level on the transition from the parameters to the top level
4798 of the function body; just tweak the flags and proceed.

4848 (poplevel): Delete #if 0 block. Make externals invisible
4849 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
4850 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
4851 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
4852 (duplicate-decls): For real parm decl after a forward decl,
4853 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

4857 local-over-local. Clarify comments.

4865 Objective C (the only user) needs.
