9311 (pushlevel): Ignore argument. Do not push another binding
9312 level on the transition from the parameters to the top level
9313 of the function body; just tweak the flags and proceed.

9363 (poplevel): Delete #if 0 block. Make externals invisible
9364 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9365 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9366 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9367 (duplicate-decls): For real parm decl after a forward decl,
9368 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

9372 local-over-local. Clarify comments.
