1988 (pushlevel): Ignore argument. Do not push another binding
1989 level on the transition from the parameters to the top level
1990 of the function body; just tweak the flags and proceed.

2040 (poplevel): Delete #if 0 block. Make externals invisible
2041 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2042 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2043 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2044 (duplicate-decls): For real parm decl after a forward decl,
2045 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
