1739 (poplevel): Delete #if 0 block. Make externals invisible
1740 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1741 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1742 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1743 (duplicate-decls): For real parm decl after a forward decl,
1744 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1748 local-over-local. Clarify comments.
