2089 (pushlevel): Ignore argument. Do not push another binding
2090 level on the transition from the parameters to the top level
2091 of the function body; just tweak the flags and proceed.

2141 (poplevel): Delete #if 0 block. Make externals invisible
2142 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2143 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2144 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2145 (duplicate-decls): For real parm decl after a forward decl,
2146 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2150 local-over-local. Clarify comments.
