1866 (poplevel): Delete #if 0 block. Make externals invisible
1867 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1868 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1869 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1870 (duplicate-decls): For real parm decl after a forward decl,
1871 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1872 foo(...) { } with only a warning. Say whether a previous
1873 declaration was implicit.
