8390 (pushlevel): Ignore argument. Do not push another binding
8391 level on the transition from the parameters to the top level
8392 of the function body; just tweak the flags and proceed.

8442 (poplevel): Delete #if 0 block. Make externals invisible
8443 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
8444 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
8445 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8446 (duplicate-decls): For real parm decl after a forward decl,
8447 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

8451 local-over-local. Clarify comments.
