10251 (pushlevel): Ignore argument. Do not push another binding

10303 (poplevel): Delete #if 0 block. Make externals invisible

10306 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10307 (duplicate-decls): For real parm decl after a forward decl,
10308 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

10320 Objective C (the only user) needs.
10321 (pushdecl_function_level): New function.
