2140 (pushlevel): Ignore argument. Do not push another binding
2141 level on the transition from the parameters to the top level
2142 of the function body; just tweak the flags and proceed.

2192 (poplevel): Delete #if 0 block. Make externals invisible
2193 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2194 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2195 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2196 (duplicate-decls): For real parm decl after a forward decl,
2197 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2201 local-over-local. Clarify comments.
