2051 (pushlevel): Ignore argument. Do not push another binding
2052 level on the transition from the parameters to the top level
2053 of the function body; just tweak the flags and proceed.

2103 (poplevel): Delete #if 0 block. Make externals invisible
2104 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2105 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2106 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2107 (duplicate-decls): For real parm decl after a forward decl,
2108 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2112 local-over-local. Clarify comments.
