10186 (pushlevel): Ignore argument. Do not push another binding

10236 (c_print_identifier): Update to match changes to struct
10238 (poplevel): Delete #if 0 block. Make externals invisible
10239 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't

10241 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10242 (duplicate-decls): For real parm decl after a forward decl,
10243 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

10253 tolerate error_mark_node being NULL.

10255 Objective C (the only user) needs.
10256 (pushdecl_function_level): New function.
