6578 (pushlevel): Ignore argument. Do not push another binding
6579 level on the transition from the parameters to the top level
6580 of the function body; just tweak the flags and proceed.

6630 (poplevel): Delete #if 0 block. Make externals invisible
6631 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6632 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6633 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6634 (duplicate-decls): For real parm decl after a forward decl,
6635 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

6639 local-over-local. Clarify comments.
