9287 (pushlevel): Ignore argument. Do not push another binding
9288 level on the transition from the parameters to the top level
9289 of the function body; just tweak the flags and proceed.

9339 (poplevel): Delete #if 0 block. Make externals invisible
9340 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9341 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9342 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9343 (duplicate-decls): For real parm decl after a forward decl,
9344 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

9348 local-over-local. Clarify comments.
