10217 (pushlevel): Ignore argument. Do not push another binding

10267 (c_print_identifier): Update to match changes to struct
10269 (poplevel): Delete #if 0 block. Make externals invisible

10273 (duplicate-decls): For real parm decl after a forward decl,
10274 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
