7544 (poplevel): Delete #if 0 block. Make externals invisible
7545 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7546 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7547 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7548 (duplicate-decls): For real parm decl after a forward decl,
7549 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
