12179 (c_print_identifier): Update to match changes to struct
12181 (poplevel): Delete #if 0 block. Make externals invisible
12182 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't

12184 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12185 (duplicate-decls): For real parm decl after a forward decl,
12186 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
